  • How to slice a list of objects in association of the object attributes

    - by gizgok
    I have a list of fixtures.Each fixture has a home club and a away club attribute.I want to slice the list in association of its home club and away club.The sliced list should be of homeclub items and awayclub items. Easier way to implement this is to first slice a list of fixtures.Then make a new list of the corresponding Home Clubs and Away Clubs.I wanted to know if we can do this one step.

  • Java copyOf method problem with an Array of Objects

    - by Greg
    elementData = Arrays.copyOf(elementData, newCapacity); Gives error: "The method copyOf(Object[], int) is undefined for the type Arrays" This was not a problem on my home computer, but at my school's it gives the error above. I'm guessing it's running an older JRE version - any workaround? Thanks

  • Business Objects ver 3 Alternate Row/Column Colors not active

    - by boxeo47
    I am converting reports from version 2 to version 3. When I select the vertical table in the report, the propeties box appears but any changes I make is not reflected in the table. If I change any attributes at the column or cell level however, the changes are taken. The problem is that some attributes like alternate row coloring are not available at the column level.

  • Creating objects makes the VM faster?

    - by Sudhir Jonathan
    Look at this piece of code: MessageParser parser = new MessageParser(); for (int i = 0; i < 10000; i++) { parser.parse(plainMessage, user); } For some reason, it runs SLOWER (by about 100ms) than for (int i = 0; i < 10000; i++) { MessageParser parser = new MessageParser(); parser.parse(plainMessage, user); } Any ideas why? The tests were repeated a lot of times, so it wasn't just random. How could creating an object 10000 times be faster than creating it once?

  • JS assignment order of properties in objects

    - by devdev
    Just had a quick question about why a certain order of assignment works and another doesn't. I wanted to create a simple "inherit" / "copy" function (just for testing it) that copies properties from one object to another: var cat = { tail:"yes", hairy:"yes, hairy" }; var dog = { sick:"extremely ill"}; function inherit(obj1, obj2) { for (var p in obj1) { obj2[p] = obj1[p]; // this works, but "obj1[p] = obj2[p];" doesn't. Why?? } } inherit(cat, dog); console.log(dog.tail);

  • C++ shared objects

    - by Klaus
    Hello, I have got four classes A, B, C and D. Class A has a member b of class B. Class B has a member c of class C. A has a member D* dpointer; This hierarchy has to be preserved (in fact this is a GUI with app, window, panel as A, B and C). Now B and C must use a method from *dpointer. Is there something more elegant than giving dpointer as a member of B and C ? Is it bad ?

  • Returning objects in php

    - by user220201
    I see similar questions asked but I seem to have problem with more basic stuff than were asked. How to declare a variable in php? My specific problem is I have a function that reads a DB table and returns the record (only one) as an object. class User{ public $uid; public $name; public $status; } function GetUserInfo($uid) { // Query DB $userObj = new User(); // convert the result into the User object. var_dump($userObj); return $userObj; } // In another file I call the above function. .... $newuser = GetUserInfo($uid); var_dump($newuser); What is the problem here, I cannot understand. Essentially the var_dump() in the function GetUserInfo() works fine. The var_dump() outside after the call to GetUserInfo() does not work. Thanks for any help. S

  • Objects in Java ArrayList don't get updated.

    - by Sbm007
    This is going to be a very long post, hopefully you can understand what I'm talking about and I appreciate any help. Thanks Basically, I've created a personal, non-commercial project (which I don't plan to release) that can read ZIP and RAR files. It can only read the contents in the archive, the folders inside, the files inside the folders and its properties (such as last modified date, last modified time, CRC checksum, uncompressed size, compressed size and file name). It can't extract files either, so it's really a ZIP/RAR viewer if you may. Anyway that's slightly irrelevant to my problem but I thought I'd give you some background info. Now for my problem: I can successfully list all the folders and files inside a ZIP archive, so now I want to take that raw input and link it together in some useful way. I made 2 classes: ArchiveFile (represents a file inside a ZIP) and ArchiveFolder (represents a folder inside a ZIP). They both have some useful methods such as getLastModifiedDate, getName, getPath and so on. But the difference is that ArchiveFolder can hold an ArrayList of ArchiveFile's and additional ArchiveFolder's (think of this as files and folders inside a folder). Now I want to populate my raw input into one root ArchiveFolder, which will have all the files in the root dir of the ZIP in the ArchiveFile's ArrayList and any additional folders in the root dir of the ZIP in the ArchiveFolder's ArrayList (and this process can continue on like this like a chain reaction (more files/folders in that ArchiveFolder etc etc). So I came up with the following code: while (archive.hasMore()) { String path = ""; ArchiveFolder current = root; String[] contents = archive.getName().split("/"); for (int x = 0; x < contents.length; ++x) { if (x == (contents.length - 1) && !archive.getName().endsWith("/")) { // If on last item and item is a file path += contents[x]; // Update final path ArchiveFile file = new ArchiveFile(path, contents[x], archive.getUncompressedSize(), archive.getCompressedSize(), archive.getModifiedTime(), archive.getModifiedDate(), archive.getCRC()); current.addFile(file); // Create and add the file to the current ArchiveFolder } else if (x == (contents.length - 1)) { // Else if we are on last item and it is a folder path += contents[x] + "/"; // Update final path ArchiveFolder folder = new ArchiveFolder(path, contents[x], archive.getModifiedTime(), archive.getModifiedDate()); current.addFolder(folder); // Create and add this folder to the current ArchiveFile } else { // Else if we are still traversing through the path path += contents[x] + "/"; // Update path ArchiveFolder folder = new ArchiveFolder(path, contents[x]); current.addFolder(folder); // Create and add folder (remember we do not know the modified date/time as all we know is the path, so we can deduce the name only) current = folder; // Update current ArchiveFolder to the newly created one for the next iteration of the for loop } } archive.getNext(); } Assume that root is the root ArchiveFolder (initially empty). And that archive.getName() returns the name of the current file OR folder in the following fashion: file.txt or folder1/file2.txt or folder4/folder2/ (this is a empty folder) etc. So basically the relative path from the root of the ZIP archive. Please read through the comments in the above code to familiarize yourself with it. Also assume that the addFolder method in an ArchiveFile, only adds the folder if it doesn't exist already (so there are no multiple folders) and it also updates the time and date of an existing folder if it is blank (ie it was a intermediate folder we only knew the name of, but now we know its details). The code for addFolder is (pretty self-explanitory): public void addFolder(ArchiveFolder folder) { int loc = folders.indexOf(folder); // folders is the ArrayList containing ArchiveFolder's if (loc == -1) { folders.add(folder); } else { ArchiveFolder real = folders.get(loc); if (real.time == null) { real.setTime(folder.getTime()); real.setDate(folder.getDate()); } } } So I can't see anything wrong with the code, it works and after finishing, the root ArchiveFolder contains all the files in the root of the ZIP as I want it to, and it contains all the direcories in the root folder as I want it to. So you'd think it works as expected, but no the ArchiveFolder's in the root folder don't contain the data inside those 'child' folders, it's just a blank folder with no additional files and folders (while it does really contain some more files/folders when viewed in WinZip). After debugging using Eclipse, the for loop does iterate through all the files (even those not included above), so this led me to believe that there is a problem with this line of the code: current = folder; What it does is, it updates the current folder (used as an intermediate by the loop) to the newly added folder. I thought Java passed by reference and thus all new operations and new additions in future ArchiveFile's and ArchiveFolder's are automatically updated, and parent ArchiveFolder's will be updated accordingly. But that does not appear to be the case? I know this is a long ass post and I really hope anyone can help me out with this. Thanks in advance.

  • Apache Mod_rewrite rule working on one server, but not another

  • PHP 5.3: Late static binding doesn't work for properties when defined in parent class while missing in child class

    - by DavidPesta
    Take a look at this example, and notice the outputs indicated. <?php class Mommy { protected static $_data = "Mommy Data"; public static function init( $data ) { static::$_data = $data; } public static function showData() { echo static::$_data . "<br>"; } } class Brother extends Mommy { } class Sister extends Mommy { } Brother::init( "Brother Data" ); Sister::init( "Sister Data" ); Brother::showData(); // Outputs: Sister Data Sister::showData(); // Outputs: Sister Data ?> My understanding was that using the static keyword would refer to the child class, but apparently it magically applies to the parent class whenever it is missing from the child class. (This is kind of a dangerous behavior for PHP, more on that explained below.) I have the following two things in mind for why I want to do this: I don't want the redundancy of defining all of the properties in all of the child classes. I want properties to be defined as defaults in the parent class and I want the child class definition to be able to override these properties wherever needed. The child class needs to exclude properties whenever the defaults are intended, which is why I don't define the properties in the child classes in the above example. However, if we are wanting to override a property at runtime (via the init method), it will override it for the parent class! From that point forward, child classes initialized earlier (as in the case of Brother) unexpectedly change on you. Apparently this is a result of child classes not having their own copy of the static property whenever it isn't explicitly defined inside of the child class--but instead of throwing an error it switches behavior of static to access the parent. Therefore, is there some way that the parent class could dynamically create a property that belongs to the child class without it appearing inside of the child class definition? That way the child class could have its own copy of the static property and the static keyword can refer to it properly, and it can be written to take into account parent property defaults. Or is there some other solution, good, bad, or ugly?

  • The right way to implement communication between java objects

    - by imoschak
    I'm working on an academic project which simulates a rather large queuing procedure in java. The core of the simulator rests within one package where there exist 8 classes each one implementing a single concept. Every class in the project follows SRP. These classes encapsulate the behavior of the simulator and inter-connect every other class in the project. The problem that I has arisen is that most of these 8 classes are, as is logical i think, tightly coupled and each one has to have working knowledge of every other class in this package in order to be able to call methods from it when needed. The application needs only one instance of each class so it might be better to create static fields for each class in a new class and use that to make calls -instead of preserving a reference in each class for every other class in the package (which I'm certain that is incorrect)-, but is this considered a correct design solution? or is there a design pattern maybe that better suits my needs?

  • How do I combine static and dynamic DHCP leases on a Cisco router?

    - by Brad
    Basically, what I need is super similar to the unanswered cisco forum question below: https://supportforums.cisco.com/message/3139749#3139749 I have a Cisco 850 Series router. I have configured a DHCP pool for the 10.0.0.0/24 network. I have excluded 10.0.0.1 - 10.0.0.99 from the DHCP pool. I want to add a static DHCP pool for stuff and I want DHCP to statically assign them the addresses of my choice below 100. Actually, I don't care what addresses I statically assign. They can be anything in the pool for all I care, I just want it to work. Why are you doing this? Just statically assign the IPs on the devices! I don't want to do this because I have some laptop users. They could obviously only use that static IP here. This isn't a problem if they could be bothered to change any location setting or something. They can't. So it HAS to be DHCP. It also has to be static IPs because I need to forward ports to them. I know, I know, this is weird but it's an apartment LAN/WLAN so this isn't exactly a typical use case. Relevant sections of config below: ip dhcp excluded-address 10.0.0.1 10.0.0.99 ! ip dhcp pool Internal-net import all network 10.0.0.0 255.255.255.0 default-router 10.0.0.1 domain-name 1770.local lease 7 ! ip dhcp pool static-pool import all origin file flash://staticmap default-router 10.0.0.1 domain-name 1770.local Contents of staticmap: *time* Aug 5 2010 09:00 AM *version* 2 !IP address Type Hardware address Lease expiration 10.0.0.100/24 1 001f.5b3e.d50a Infinite *end* You can see here I was trying addresses outside the excluded-address range to see if that would make any difference. My testing machine's MAC: mainframe:~ brad$ ifconfig en1 en1: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500 ether 00:1f:5b:3e:d5:0a What shows up in the DHCP binding table: basestar#show ip dhcp binding Bindings from all pools not associated with VRF: IP address Client-ID/ Lease expiration Type Hardware address/ User name 10.0.0.112 0100.1f5b.3ed5.0a Aug 12 2010 10:06 AM Automatic What's up with the funny looking MAC in the DHCP binding table?? Is what I'm trying to accomplish basically impossible? Am I going about this the wrong way? All I want to to be able to port forward some ports to specific devices. The way I would do this with a consumer router is to do what I'm trying to do here; assign static DHCP to those devices then configure PAT for ports on those addresses.

  • Using Instance Nodes, worth it?

    - by Twitch
    I am making a 2d game where there are various environments with lots and lots of objects. There is a forest scene with like 1200 objects in total(trees mainly), of which around 100 are visible on the camera at any given time, as you move through the level. These are comprised of around 20 different kind of trees and other props. Each object is usually 2-6 triangles with a transparent texture. My developer asked me to replace each object in the scene with a node, and keeping only a minimal amount of actual objects which would be 300+ or so(?), since there are a few modified unique meshes. So he can instantiate the actual objects to keep the game light. Is this actually effective? And if so how much? I 've read about draw calls and such and I suppose that if I combine each texture (10 kinds of trees) in 1 mesh it will have the same effect?

  • Combining lists of objects containing lists of objects in c#

    - by Dan H
    The title is a little prosaic, I know. I have 3 classes (Users, Cases, Offices). Users and Cases contain a list of Offices inside of them. I need to compare the Office lists from Users and Cases and if the ID's of Offices match, I need to add those IDs from Cases to the Users. So the end goal is to have the Users class have any Offices that match the Offices in the Cases class. Any ideas? My code (which isnt working) foreach (Users users in userList) foreach (Cases cases in caseList) foreach (Offices userOffice in users.officeList) foreach (Offices caseOffice in cases.officeList) { if (userOffice.ID == caseOffice.ID) users.caseAdminIDList.Add(cases.adminID); }//end foreach //start my data classes class Users { public Users() { List<Offices> officeList = new List<Offices>(); List<int> caseAdminIDList = new List<int>(); ID = 0; }//end constructor public int ID { get; set; } public string name { get; set; } public int adminID { get; set; } public string ADuserName { get; set; } public bool alreadyInDB { get; set; } public bool alreadyInAdminDB { get; set; } public bool deleted { get; set; } public List<int> caseAdminIDList { get; set; } public List<Offices> officeList { get; set; } } class Offices { public int ID { get; set; } public string name { get; set; } } class Users { public Users() { List<Offices> officeList = new List<Offices>(); List<int> caseAdminIDList = new List<int>(); ID = 0; }//end constructor public int ID { get; set; } public string name { get; set; } public int adminID { get; set; } public string ADuserName { get; set; } public bool alreadyInDB { get; set; } public bool alreadyInAdminDB { get; set; } public bool deleted { get; set; } public List<int> caseAdminIDList { get; set; } public List<Offices> officeList { get; set; } }

  • LINQ to Objects .Distinct() not pulling distinct objects

    - by Anthony Potts
    I have two ways that I am doing a fuzzy search for a customer. One is by an abbreviated name and the other is by the customers full name. When I take these two and then union them together (which I have read several places should remove distinct values) I get duplicates. Thinking that all I need to do is then call the .Distinct() method on this I also still get Duplicates. Do I need to implement some compare functionality in my customer object? My code: Dim shortNameMatch As List(Of ICustomer) = CustomerLibrary.GetCustomersByShortName(term) Dim custNameMatch As List(Of ICustomer) = CustomerLibrary.GetCustomersByCustName(term) Dim allMatch = (From a In (From s In shortNameMatch Select s).Union(From c In custNameMatch Select c) Select a).Distinct()

  • How to route public static IP to a virtual machine on a vmware ESXi host?

    - by Kevin Southworth
    I have 5 static IPs from my ISP (Comcast) and I have a physical machine with VMware ESXi 4.0 on it that is hosting multiple virtual machines. Right now I am just using the default vmware virtual network (vswitch0) with DHCP from the Comcast IP Gateway Router and everything is working fine. Each virtual machine can access the internet, etc. One of my virtual machines is a webserver (Windows Server 2008) and I want to assign it to 1 of my 5 static IPs so it's accessible from the public internet, while leaving the other VMs on the internal LAN still using DHCP. If I just plug my laptop directly into the Comcast IP Gateway (it has 4 ports on the back) and assign my laptop a Static IP using the windows networking dialogs, then I can hit my laptop from the public internet and it works great. However, if I try to do the same steps to set a static IP config on my Windows Server 2008 VM, it does not work. The VM cannot access the internet (open Firefox and try to visit google.com), and I cannnot see the VM from the public internet either. I'm assuming I'm missing something in the ESXi config somewhere, but I'm pretty new to ESXi and I'm not sure how to configure it to work this way.

  • static block instance block java Order

    - by Rollerball
    Having read this question In what order are the different parts of a class initialized when a class is loaded in the JVM? and the related JLS. I would like to know in more detail why for example having class Animal (superclass) and class Dog (subclass) as following: class Animal { static{ System.out.println("This is Animal's static block speaking"): } { System.out.println("This is Animal's instance block speaking"); } class Dog{ static{ System.out.println("This is Dog's static block speaking"); } { System.out.println("This is Dog's instance block speaking"); } public static void main (String [] args) { Dog dog = new Dog(); } } Ok before instantiating a class its direct superclass needs to be initialized (therefore all the statics variables and block need to be executed). So basically the question is: Why after initializing the static variables and static blocks of the super class, control goes down to the subclass for static variables initialization rather then finishing off the initialization of also the instance member? The control goes like: superclass (Animal): static variables and static blocks subclass (Dog): static variables and static blocks superclass (Animal): instance variables and instance blocks sublcass (Dog):instance variables and instance blocks What is the reason why it is in this way rather than : superclass -> static members superclass -> instance members subclass -> static members sublcass-> instance members

  • Hibernate Query for a List of Objects that matches a List of Objects' ids

    - by sal
    Given a classes Foo, Bar which have hibernate mappings to tables Foo, A, B and C public class Foo { Integer aid; Integer bid; Integer cid; ...; } public class Bar { A a; B b; C c; ...; } I build a List fooList of an arbitrary size and I would like to use hibernate to fetch List where the resulting list will look something like this: Bar[1] = [X1,Y2,ZA,...] Bar[2] = [X1,Y2,ZB,...] Bar[3] = [X1,Y2,ZC,...] Bar[4] = [X1,Y3,ZD,...] Bar[5] = [X2,Y4,ZE,...] Bar[6] = [X2,Y4,ZF,...] Bar[7] = [X2,Y5,ZG,...] Bar[8] = ... Where each Xi, Yi and Zi represents a unique object. I know I can iterate fooList and fetch each List and call barList.addAll(...) to build the result list with something like this: List<bar> barList.addAll(s.createQuery("from Bar bar where bar.aid = :aid and ... ") .setEntity("aid", foo.getAid()) .setEntity("bid", foo.getBid()) .setEntity("cid", foo.getCid()) .list(); ); Is there any easier way, ideally one that makes better use of hibernate and make a minimal number of database calls? Am I missing something? Is hibernate not the right tool for this?

  • creating BeanInfo objects in NetBeans 6.1 does not work for some objects

    - by Coder
    I have recently learned about BeanInfo classes in Java, and have successfully used them to add icons to my custom GUI components which extend swing components such as JTextField, however i have a more specialized GUI component which extends from another one of my GUI components, which then extends from JTextField. Ie. the class hierarchy is of the form "A - B - JTextField". I can create a bean info object that works for class B, but when i click on the bean info editor option in netbeans to create a bean info object for class A, nothing happens. Ie. there is no error pop-up and a bean info object is not created. There isn't much difference between class A and B. Both A and B have default no argument constructors and they are very similar to each other. The only thing i can really think of is that A uses generics and B does not. I would like to create a beaninfo object for class A so that i can add custom icons for that component. Any help would be appreciated. Thanks.

  • What is a good use case for static import of methods?

    - by Miserable Variable
    Just got a review comment that my static import of the method was not a good idea. The static import was of a method from a DA class, which has mostly static methods. So in middle of the business logic I had a da activity that apparently seemed to belong to the current class: import static some.package.DA.*; class BusinessObject { void someMethod() { .... save(this); } } The reviewer was not keen that I change the code and I didn't but I do kind of agree with him. One reason given for not static-importing was it was confusing where the method was defined, it wasn't in the current class and not in any superclass so it too some time to identify its definition (the web based review system does not have clickable links like IDE :-) I don't really think this matters, static-imports are still quite new and soon we will all get used to locating them. But the other reason, the one I agree with, is that an unqualified method call seems to belong to current object and should not jump contexts. But if it really did belong, it would make sense to extend that super class. So, when does it make sense to static import methods? When have you done it? Did/do you like the way the unqualified calls look? EDIT: The popular opinion seems to be that static-import methods if nobody is going to confuse them as methods of the current class. For example methods from java.lang.Math and java.awt.Color. But if abs and getAlpha are not ambiguous I don't see why readEmployee is. As in lot of programming choices, I think this too is a personal preference thing. Thanks for your response guys, I am closing the question.

  • Why is my eth0 getting a dynamic ip when it is configured to be static?

    - by sdek
    For some reason our office linux box is being assigned an ip address via dhcp and I don't know why. What is confusing to me is that when I check system-config-network it shows that my eth0 is setup to be a static ip address. And /etc/sysconfig/network-scripts/ifcfg-eth0 also shows it is setup to be a static ip, yet it is getting a different ip address than the one specified in the ifcfg-eth0. Let me know if you have any suggestions on or ideas on where I can look next. Here are a few details that might help you figure out what an idiot I am :) Fedora 11 Router in front of this box is running dhcp, starting at 10.42.1.100 This box is configured to be 10.42.1.50 (at least I think it is!), subnet 255.255.255.0 (which is same as the router's lan subnet) Instead of having the static IP, this box is getting assigned 10.42.1.100. Here are the ifcfg-eth0 details DEVICE=eth0 BOOTPROTO=none ONBOOT=yes TYPE=Ethernet USERCTL=no NM_CONTROLLED=no NETMASK=255.255.255.0 IPADDR=10.42.1.50 GATEWAY=10.42.1.1

  • How do i mitigate DDOS attacks on static servers?

    - by acidzombie24
    Here is a slightly different take on DDOS attacks. Rather than a server with dynamic content being attack i was curious how to deal with attacks on servers with STATIC CONTENT. This means cpu tends to not be an issue. Its either bandwidth or connection problems. How would i mitigate a DDOS attack knowing nothing about the attacker (for example country, ip address or anything else). I was wondering is shorting the timeout and increasing amount of connections is an acceptable solution? Or maybe that is completely useless? Also i would limit the amount of connections per IP address. Would the above help or be pointless? Keeping in mind everything is static checking for multiple request of the same page (html, css, js, etc) could be a sign of a attack. What are some measures i can take on a static content server?
