  • C# Generic new() constructor problem

    - by LB
    I'm trying to create a new object of type T via its constructor when adding to the list. I'm getting a compile error: The correct error message is: 'T': cannot provide arguments when creating an instance of a variable But it does! Any ideas? public static string GetAllItems<T>(...) where T : new() { ... List<T> tabListItems = new List<T>(); foreach (ListItem listItem in listCollection) { tabListItems.Add(new T(listItem)); // error here. } ... }

  • Generic usercontrol possible?

    - by Sam
    Since .Net 4 does support generics in XAML, I'd like to create a UserControl using generics, like: public class MyComboBox<T> { } I can declare the UserControl quite well, but how would I use it in a XAML file? Or can't this be done in XAML?

  • Ubuntu 12.04 + Raid0 + Windows 7 not loading

    - by Douglas
    please someone help me.... (Sorry for my english) Hi, I have a Pc with 2 Hd (1Tb each) on Raid0. I had a Windows 7 64bits working for several months. When I installed the Windows I let a 100Gb partition empty to install Ubuntu someday. I was using Linux on a Virtualbox, but this week I tried to install Ubuntu 12.04 in this 100Gb partition. I used the Ubuntu alternate cd, because the 'normal' cd was giving me trouble with the Raid0. The grub installation always reported a error. After a lot of work I found that I nedded to install grub on partition /dev/mapper/isw_chjbfeec_DougRaid1 (see Bootinfo below). The Windows installation created a 100Mb boot partition, so I needed to install grub in this partition. Now I have the Ubuntu working 100% ok. The problem is, the Windows is not booting! The windows option is present on the grub menu, but when I choose the windows option there is a black screen and after that the grub is reloaded. My Bootinfo is: Boot Info Script 0.61 [1 April 2012] ============================= Boot Info Summary: =============================== => Grub2 (v1.99) is installed in the MBR of /dev/sda and looks at sector 1 of the same hard drive for core.img. core.img is at this location and looks in partition 1 for /boot/grub. => Grub2 (v1.99) is installed in the MBR of /dev/mapper/isw_chjbfeec_DougRaid and looks at sector 1 of the same hard drive for core.img. core.img is at this location and looks in partition 1 for /boot/grub. sda1: __________________________________________________________________________ File system: Boot sector type: Unknown Boot sector info: Mounting failed: mount: unknown filesystem type '' sda2: __________________________________________________________________________ File system: Boot sector type: Unknown Boot sector info: Mounting failed: mount: unknown filesystem type '' mount: unknown filesystem type '' sda3: __________________________________________________________________________ File system: Extended Partition Boot sector type: Unknown Boot sector info: isw_chjbfeec_DougRaid1: ________________________________________________________ File system: ntfs Boot sector type: Grub2 (v1.99) Boot sector info: Grub2 (v1.99) is installed in the boot sector of isw_chjbfeec_DougRaid1 and looks at sector 3841862992 of the same hard drive for core.img. core.img is at this location and looks for (,msdos5)/boot/grub on this drive.

  • VB.NET, make a function with return type generic ?

    - by Quandary
    Currently I have written a function to deserialize XML as seen below. How do I change it so I don't have to replace the type every time I want to serialize another object type ? The current object type is cToolConfig. How do I make this function generic ?

  • System will not boot without USB thumb drive inserted

    - by agent154
    I've had this issue before when trying out Linux Mint, but I was unable to get any assistance. I was then lead to believe that it was a problem related to Mint, and not grub. I installed Ubuntu 12.04 tonight on a second partition alongside Windows 7. I installed from a USB stick, and everything went peachy until I rebooted without the stick in my tower. It now says: error: no such device: 20cec6ca-4024-4237-84c3-2dba3c851497 grub rescue > I've verified via ls -l /dev/disk/by-uuid that my drive where Ubuntu is installed matches the UUID that supposedly doesn't exist. The UUID of my thumb drive when inserted happens to be 06B3-9C68. There is no mention of my USB drive's UUID anywhere in /boot/grub/grub.cfg I've also tried to re-install GRUB after booting into my system, removing the stick, and running grub-install /dev/sda. It still happens, and I cannot boot without the USB drive inserted into the computer. And what really gets my goat is that the boot order of my system is CDROMHard DriveUSB. It's not even reaching the USB to try to boot from it, so why does it matter that it's not there? Edit: Also, I ran grub-config without the stick in followed by another grub-install. Still no go. FWIW, here's my grub.cfg file: # # DO NOT EDIT THIS FILE # # It is automatically generated by grub-mkconfig using templates # from /etc/grub.d and settings from /etc/default/grub # ### BEGIN /etc/grub.d/00_header ### if [ -s $prefix/grubenv ];

    thanks for your time and reading this, here's the deal: i upgraded from 11.10 to 12.04 and everything worked out until i rebooted, i had 11.10 sucessfully running as a dual boot with windows vista. when i rebooted, my GRUB was shot to hell, what ever option i selected it said partion not found or something similar... booting into a live version on a thumb drive and running bootrepair from there fixed the issue... but only for ubuntu, when i try to boot into windows it only goes back to GRUB. i'm not at home, and heres a list of what i have here with me... 1 4gb thumb drive, empty 1 8gb thumb drive, windows vista installer bootable 1 old laptop, the one i try to save, optical drive is not existent 2 Mbps internet connection can you help me get back into my windows without having to reinstall windows? or at least show me a way how to use my illustrator through a virtual machine or something? here's my grub cfg # # DO NOT EDIT THIS FILE # # It is automatically generated by grub-mkconfig using templates # from /etc/grub.d and settings from /etc/default/grub # ### BEGIN /etc/grub.d/00_header ### if [ -s $prefix/grubenv ];

  • Represent multiple Null/Generic objects in an ActiveRecord association?

    - by slothbear
    I have a Casefile model that belongs_to a Doctor. In additional to all the "real" doctors, there are several generic Doctors: "self-treated", "not specified", and "removed" (it used to have a real doctor, but no longer does). I suspect there will be even more generic values in the future. I started with special "doctors" in the database, generated from seed. The generic Doctors only need to respond to the "name" and "real_doctor?" methods. This worked with one, was strained with two, and now feels completely broken. I want to change the behavior and can't figure out how to test it, a bad sign. Creating all the generic objects for testing is also trouble, including fake values to pass validation of the required Doctor attributes. The Null Object pattern works well for one generic object. The "name" method could check casefile.doctor.nil? and return "self-treated", as demonstrated by Craig Ambrose. What pattern should I use when there are multiple generic objects with very limited state?

  • How to use generic (NSObject) controller with subviews of a UIViewController?

    - by wanderlust
    I have a UIViewController that is loading several subviews at different times based on user interaction. I originally built all of these subviews in code, with no nib files. Now I am moving to nib files with custom UIView subclasses. Some of these subviews display static data, and I am using loadNibNamed:owner:options: to load them into the view controller. Others contain controls that I need to access. I (sort of) understand the reasons Apple says to use one view controller per screen of content, using generic controller objects (NSObjects) to manage subsections of a screen. So I need a view controller, a generic controller, a view class and a nib. How do I put this all together? My working assumptions and subsequent questions: I will associate the view class with the nib in the 'class identity' drop down in IB. The view controller will coordinate overall screen interactions. When necessary, it will create an instance of the generic controller. Does the generic controller load the nib? How? Do I define the outlets and actions in that view class, or should they be in the generic controller? How do I pass messages between the view controller and the generic controller? If anyone can point me to some sample code using a controller in this way, it will go a long way to helping me understand. None of the books or stackoverflow posts I've read have quite hit the spot yet.

  • straight to grub prompt on boot

    - by cheshirekow
    I am very lost. I did a fresh install of Ubuntu 10.04 on a laptop. First reboot was fine. I ran all the recommended upgrades, and now every time I start I get just a grub>_ prompt. No error message, just the prompt, and a little banner at the top saying grub's version and telling me that I have minimal bash style editing. I've tried: 1) Re-installing grub via sudo grub-install sda (There is only one disk with only two partitions, one primary, and one for swap) 2) Changed GRUB_HIDDEN_TIMEOUT=10 GRUB_TIMEOUT=30 GRUB_CMDLINE_LINUX_DEFAULT="rootdelay=90" GRUB_CMDLINE_LINUX="rootdelay=90" in /etc/default/grub. No luck. I can boot with the following: grub> set root=(hd0,1) grub> probe (hd0,1) -u c00fadde-f7e8-45e7-a4da-0235605f756 grub> linux /boot/vmlinuz-2.6.32-21-generic root=UUID=c00fadde-f7e8-45e7-a4da-0235605f756 rootdelay=90 grub> initrd /boot/initrd.img-2.6.32-21-generic grub> boot And then everything seems to be fine from there. From the grub prompt if I try configfile /boot/grub/grub.cfg The screen clears and I get another grub prompt.

  • On installing nvidia drivers on 12.10 I get "Bad return status for module build on kernel: 3.5.0-19-generic (x86_64)"

    - by james
    New Ubuntu user - just recently made the mistake of trying a different nvidia driver. I'd managed to get the last (nvidia-current) one working through software sources a few weeks ago. The other day I tried to cross over to nvidia-experimental-310 and this produced a system error. Swapping back and forth between proprietary drivers now always causes an error and I can't get any of them to work. Installing through the terminal I get this error message every time: Building initial module for 3.5.0-19-generic Error! Bad return status for module build on kernel: 3.5.0-19-generic (x86_64) Consult /var/lib/dkms/nvidia-experimental-310/310.14/build/make.log for more information On rebooting, I end up with the crappy screen resolution and the thick black border around the screen. I use gksudo software-properties-gtk to bring up sources, where I can change back to the nouveau driver, which restores my screen. After that I can't find /var/lib/dkms/nvidia-experimental-310/310.14/build/make.log so I can't tell you what's inside. Any ideas what might be preventing the nvidia driver from installing? SOLUTION FOUND Okay - so I have a workaround. This is what has worked: Upgrade to kernel 3.7.0 as detailed here upgrade to latest version of the nvidia drivers as detailed here No idea what was happening with kernel 3.5.0-19, but this seems to be better. A little slower maybe on boot, but after days of messing around it's nice to have something that works.

  • 64-bit 13.10 shows 1GB less RAM than 64-bit 13.04 did

    - by kiloseven
    Multiple 64-bit versions (Kubuntu, Lubuntu and Xubuntu) once installed on my ThinkPad R60 show 3GB of RAM, not the correct 4GB of RAM. Last week with 13.04, I had 4GB of RAM (which matches the BIOS) and this week I have 3GB available. Inquiring minds want to know.

  • Broken package after update: linux-headers, error brokencount >0

    - by escozul
    Ubuntu 12.04. After an update, I get a red warning icon in the system tray, warning about an error: broken count 0 Opening Update manager, I see that the broken package is linux-headers-3.2.0-33-generic-pae (new install) Specificaly I have my ubuntu on an AspireOne with 8gb internal storage. I tried apt-get clean as suggested in another question on this site, and tried reinstalling the package in Synaptic. I have tried to reboot but to no avail. I have also tried apt-get install --fix-broken and I get the following: sudo apt-get install --fix-broken [sudo] password for elina: Reading package lists...

The broken package is linux-headers-3.2.0-33-generic-pae_3.2.0-33.52_i386.deb which only takes up 11.3Mb on my hard drive. I'm soooo lost. I really hope there is something I'm missing here. I don't want to go about reformatting this bucket. It's really not worth the time. Any help for fixing this would be hot.

  • 12.04 upgrade broke grub? (not wubi related)

    - by kaare
    I just updated from 11.10 to 12.04, with no major problems (it took a while to get past a request to restart ssh, mysql and some other services, but I did no fiddling by myself, everything was done by the installer). However, after restarting, grub can't do anything. Picking the new linux installation (first entry), I just get error: no such partition error: no such partition error: no such partition and picking the recovery-version just gives 5 lines instead of 3. I have windows 7 installed on a different drive, and can run it by booting from that drive instead. Picking it from the grub menu gives the same error as above (can't remember how many lines, though). I'll be honest and say that I don't remember if win 7 could be booted from grub before the update, though. In short, nothing on the grub menu works. any solutions? The grub menu changed appearance - before it was on a purple background, small letters, now it's white-on-black, big letters, looking very basic. The original installation was from a usb-drive, and I hadn't heard about wubi until I started googling this problem, so I doubt there's any connection. I really hope there are some grub-savvy people out there :) EDIT: ok. so, I made a bootable usb, and am running from that right now. when I ran the bootinfoscript, it warned me that "gawk" could not be found, using "busybox awk" instead.

  • C#/.NET Fundamentals: Choosing the Right Collection Class

    - by James Michael Hare
    The .NET Base Class Library (BCL) has a wide array of collection classes at your disposal which make it easy to manage collections of objects. While it's great to have so many classes available, it can be daunting to choose the right collection to use for any given situation. As hard as it may be, choosing the right collection can be absolutely key to the performance and maintainability of your application! This post will look at breaking down any confusion between each collection and the situations in which they excel. We will be spending most of our time looking at the System.Collections.Generic namespace, which is the recommended set of collections. The Generic Collections: System.Collections.Generic namespace The generic collections were introduced in .NET 2.0 in the System.Collections.Generic namespace. This is the main body of collections you should tend to focus on first, as they will tend to suit 99% of your needs right up front. It is important to note that the generic collections are unsynchronized. This decision was made for performance reasons because depending on how you are using the collections its completely possible that synchronization may not be required or may be needed on a higher level than simple method-level synchronization. Furthermore, concurrent read access (all writes done at beginning and never again) is always safe, but for concurrent mixed access you should either synchronize the collection or use one of the concurrent collections. So let's look at each of the collections in turn and its various pros and cons, at the end we'll summarize with a table to help make it easier to compare and contrast the different collections. The Associative Collection Classes Associative collections store a value in the collection by providing a key that is used to add/remove/lookup the item. Hence, the container associates the value with the key. These collections are most useful when you need to lookup/manipulate a collection using a key value. For example, if you wanted to look up an order in a collection of orders by an order id, you might have an associative collection where they key is the order id and the value is the order. The Dictionary<TKey,TVale> is probably the most used associative container class. The Dictionary<TKey,TValue> is the fastest class for associative lookups/inserts/deletes because it uses a hash table under the covers. Because the keys are hashed, the key type should correctly implement GetHashCode() and Equals() appropriately or you should provide an external IEqualityComparer to the dictionary on construction. The insert/delete/lookup time of items in the dictionary is amortized constant time - O(1) - which means no matter how big the dictionary gets, the time it takes to find something remains relatively constant. This is highly desirable for high-speed lookups. The only downside is that the dictionary, by nature of using a hash table, is unordered, so you cannot easily traverse the items in a Dictionary in order. The SortedDictionary<TKey,TValue> is similar to the Dictionary<TKey,TValue> in usage but very different in implementation. The SortedDictionary<TKey,TValye> uses a binary tree under the covers to maintain the items in order by the key. As a consequence of sorting, the type used for the key must correctly implement IComparable<TKey> so that the keys can be correctly sorted. The sorted dictionary trades a little bit of lookup time for the ability to maintain the items in order, thus insert/delete/lookup times in a sorted dictionary are logarithmic - O(log n). Generally speaking, with logarithmic time, you can double the size of the collection and it only has to perform one extra comparison to find the item. Use the SortedDictionary<TKey,TValue> when you want fast lookups but also want to be able to maintain the collection in order by the key. The SortedList<TKey,TValue> is the other ordered associative container class in the generic containers. Once again SortedList<TKey,TValue>, like SortedDictionary<TKey,TValue>, uses a key to sort key-value pairs. Unlike SortedDictionary, however, items in a SortedList are stored as an ordered array of items. This means that insertions and deletions are linear - O(n) - because deleting or adding an item may involve shifting all items up or down in the list. Lookup time, however is O(log n) because the SortedList can use a binary search to find any item in the list by its key. So why would you ever want to do this? Well, the answer is that if you are going to load the SortedList up-front, the insertions will be slower, but because array indexing is faster than following object links, lookups are marginally faster than a SortedDictionary. Once again I'd use this in situations where you want fast lookups and want to maintain the collection in order by the key, and where insertions and deletions are rare. The Non-Associative Containers The other container classes are non-associative. They don't use keys to manipulate the collection but rely on the object itself being stored or some other means (such as index) to manipulate the collection. The List<T> is a basic contiguous storage container. Some people may call this a vector or dynamic array. Essentially it is an array of items that grow once its current capacity is exceeded. Because the items are stored contiguously as an array, you can access items in the List<T> by index very quickly. However inserting and removing in the beginning or middle of the List<T> are very costly because you must shift all the items up or down as you delete or insert respectively. However, adding and removing at the end of a List<T> is an amortized constant operation - O(1). Typically List<T> is the standard go-to collection when you don't have any other constraints, and typically we favor a List<T> even over arrays unless we are sure the size will remain absolutely fixed. The LinkedList<T> is a basic implementation of a doubly-linked list. This means that you can add or remove items in the middle of a linked list very quickly (because there's no items to move up or down in contiguous memory), but you also lose the ability to index items by position quickly. Most of the time we tend to favor List<T> over LinkedList<T> unless you are doing a lot of adding and removing from the collection, in which case a LinkedList<T> may make more sense. The HashSet<T> is an unordered collection of unique items. This means that the collection cannot have duplicates and no order is maintained. Logically, this is very similar to having a Dictionary<TKey,TValue> where the TKey and TValue both refer to the same object. This collection is very useful for maintaining a collection of items you wish to check membership against. For example, if you receive an order for a given vendor code, you may want to check to make sure the vendor code belongs to the set of vendor codes you handle. In these cases a HashSet<T> is useful for super-quick lookups where order is not important. Once again, like in Dictionary, the type T should have a valid implementation of GetHashCode() and Equals(), or you should provide an appropriate IEqualityComparer<T> to the HashSet<T> on construction. The SortedSet<T> is to HashSet<T> what the SortedDictionary<TKey,TValue> is to Dictionary<TKey,TValue>. That is, the SortedSet<T> is a binary tree where the key and value are the same object. This once again means that adding/removing/lookups are logarithmic - O(log n) - but you gain the ability to iterate over the items in order. For this collection to be effective, type T must implement IComparable<T> or you need to supply an external IComparer<T>. Finally, the Stack<T> and Queue<T> are two very specific collections that allow you to handle a sequential collection of objects in very specific ways. The Stack<T> is a last-in-first-out (LIFO) container where items are added and removed from the top of the stack. Typically this is useful in situations where you want to stack actions and then be able to undo those actions in reverse order as needed. The Queue<T> on the other hand is a first-in-first-out container which adds items at the end of the queue and removes items from the front. This is useful for situations where you need to process items in the order in which they came, such as a print spooler or waiting lines. So that's the basic collections. Let's summarize what we've learned in a quick reference table.  Collection Ordered? Contiguous Storage? Direct Access? Lookup Efficiency Manipulate Efficiency Notes Dictionary No Yes Via Key Key: O(1) O(1) Best for high performance lookups. SortedDictionary Yes No Via Key Key: O(log n) O(log n) Compromise of Dictionary speed and ordering, uses binary search tree. SortedList Yes Yes Via Key Key: O(log n) O(n) Very similar to SortedDictionary, except tree is implemented in an array, so has faster lookup on preloaded data, but slower loads. List No Yes Via Index Index: O(1) Value: O(n) O(n) Best for smaller lists where direct access required and no ordering. LinkedList No No No Value: O(n) O(1) Best for lists where inserting/deleting in middle is common and no direct access required. HashSet No Yes Via Key Key: O(1) O(1) Unique unordered collection, like a Dictionary except key and value are same object. SortedSet Yes No Via Key Key: O(log n) O(log n) Unique ordered collection, like SortedDictionary except key and value are same object. Stack No Yes Only Top Top: O(1) O(1)* Essentially same as List<T> except only process as LIFO Queue No Yes Only Front Front: O(1) O(1) Essentially same as List<T> except only process as FIFO   The Original Collections: System.Collections namespace The original collection classes are largely considered deprecated by developers and by Microsoft itself. In fact they indicate that for the most part you should always favor the generic or concurrent collections, and only use the original collections when you are dealing with legacy .NET code. Because these collections are out of vogue, let's just briefly mention the original collection and their generic equivalents: ArrayList A dynamic, contiguous collection of objects. Favor the generic collection List<T> instead. Hashtable Associative, unordered collection of key-value pairs of objects. Favor the generic collection Dictionary<TKey,TValue> instead. Queue First-in-first-out (FIFO) collection of objects. Favor the generic collection Queue<T> instead. SortedList Associative, ordered collection of key-value pairs of objects. Favor the generic collection SortedList<T> instead. Stack Last-in-first-out (LIFO) collection of objects. Favor the generic collection Stack<T> instead. In general, the older collections are non-type-safe and in some cases less performant than their generic counterparts. Once again, the only reason you should fall back on these older collections is for backward compatibility with legacy code and libraries only. The Concurrent Collections: System.Collections.Concurrent namespace The concurrent collections are new as of .NET 4.0 and are included in the System.Collections.Concurrent namespace. These collections are optimized for use in situations where multi-threaded read and write access of a collection is desired. The concurrent queue, stack, and dictionary work much as you'd expect. The bag and blocking collection are more unique. Below is the summary of each with a link to a blog post I did on each of them. ConcurrentQueue Thread-safe version of a queue (FIFO). For more information see: C#/.NET Little Wonders: The ConcurrentStack and ConcurrentQueue ConcurrentStack Thread-safe version of a stack (LIFO). For more information see: C#/.NET Little Wonders: The ConcurrentStack and ConcurrentQueue ConcurrentBag Thread-safe unordered collection of objects. Optimized for situations where a thread may be bother reader and writer. For more information see: C#/.NET Little Wonders: The ConcurrentBag and BlockingCollection ConcurrentDictionary Thread-safe version of a dictionary. Optimized for multiple readers (allows multiple readers under same lock). For more information see C#/.NET Little Wonders: The ConcurrentDictionary BlockingCollection Wrapper collection that implement producers & consumers paradigm. Readers can block until items are available to read. Writers can block until space is available to write (if bounded). For more information see C#/.NET Little Wonders: The ConcurrentBag and BlockingCollection Summary The .NET BCL has lots of collections built in to help you store and manipulate collections of data. Understanding how these collections work and knowing in which situations each container is best is one of the key skills necessary to build more performant code. Choosing the wrong collection for the job can make your code much slower or even harder to maintain if you choose one that doesn’t perform as well or otherwise doesn’t exactly fit the situation. Remember to avoid the original collections and stick with the generic collections.  If you need concurrent access, you can use the generic collections if the data is read-only, or consider the concurrent collections for mixed-access if you are running on .NET 4.0 or higher.   Tweet Technorati Tags: C#,.NET,Collecitons,Generic,Concurrent,Dictionary,List,Stack,Queue,SortedList,SortedDictionary,HashSet,SortedSet

  • Why does linux-image-virtual depend on a generic kernel now?

    - by ændrük
    The linux-image-virtual metapackage has historically provided a kernel that is specifically designed for use in virtual machines: Ubuntu 8.04: linux-image-2.6.24-32-virtual Ubuntu 10.04: linux-image-2.6.32-44-virtual Ubuntu 11.10: linux-image-3.0.0-26-virtual Ubuntu 12.04: linux-image-3.2.0-32-virtual Apparently, this has now changed: Ubuntu 12.10: linux-image-3.5.0-17-generic What's the explanation? Is this still the correct kernel to use in a virtual machine?

  • Why is lowlatency kernel not being updated in parallel with the generic kernel?

    - by FlabbergastedPickle
    All, Any idea when we'll see updates to the lowlatency version of the Ubuntu 12.04 kernel? It is still stuck at 3.2.0.23 whereas the generic kernel is already several updates ahead of it at a version 3.2.0.25? NB: I am using a 64-bit version but I don't think this is limited to the 64-bit kernels alone but rather affects both 32-bit and 64-bit builds. Please do correct me if I am wrong about this.

  • Should I have a separate method for Update(), Insert(), etc., or have a generic Query() that would be able to handle all of these?

    - by Prayos
    I'm currently trying to write a class library for a connection to a database. Looking over it, there are several different types of queries: Select From, Update, Insert, etc. My question is, what is the best practice for writing these queries in a C# application? Should I have a separate method for each of them(i.e. Update(), Insert()), or have a generic Query() that would be able to handle all of these? Thanks for any and all help!

What I am trying to do is to reproduce the html inside Ember.View.render, but I would like to reuse as much Ember functionality as possible. Specifically, I would like to reuse the {{#linkTo ...}} helper, with two goals: Reuse existing html rendering implemented in the {{#linkTo ...}} helper Get the same routing support that using the {{#linkTo ...}} in a template provides. How can I call this helper from within javascript code? This is my first (incomplete) attempt. The template: {{view SettingsApp.NavigationView}} And the view: var trans = Ember.I18n.t; var MAIN_MENU = [ { 'linkTo' : 'nodes', 'i-class' : 'icon-cloud', 'txt' : trans('generic.nodes') }, { 'linkTo' : 'services', 'i-class' : 'icon-phone', 'txt' : trans('generic.services') }, ]; function getNavIcon (data) { var linkTo = data.linkTo, i_class = data['i-class'], txt = data.txt; var html = '<i class="icon-fixed-width icon-2x ' + i_class + '"></i>&nbsp;&nbsp;' + txt; return html; } SettingsApp.NavigationView = Ember.View.extend({ menu : MAIN_MENU, render: function(buffer) { for (var i=0, l=this.menu.length; i<l; i++) { var data = this.menu[i]; // TODO: call the ember function implementing the {{#linkTo ...}} helper buffer.push(getNavIcon(data)); } return buffer; } });
