  • Java iteration reading & parsing

    - by Patrick Lorio
    I have a log file that I am reading to a string public static String Read (String path) throws IOException { StringBuilder sb = new StringBuilder(); InputStream in = new BufferedInputStream(new FileInputStream(path)); int r; while ((r = in.read()) != -1) { sb.append(r); } return sb.toString(); } Then I have a parser that iterates over the entire string once void Parse () { String con = Read("log.txt"); for (int i = 0; i < con.length; i++) { /* parsing action */ } } This is hugely a waste of cpu cycles. I loop over all the content in Read. Then I loop over all the content in Parse. I could just place the /* parsing action */ under the while loop in the Read method, which would be find but I don't want to copy the same code all over the place. How can I parse the file in one iteration over the contents and still have separate methods for parsing and reading? In C# I understand there is some sort of yield return thing, but I'm locked with Java. What are my options in Java?

  • Objective C Object Functioning & Passing Arrays

    - by Patrick
    I apologise if this has been asked before but I can't find the info I need. Basically I want a UITableView to be populated using info from a server, similar to the SeismicXML example. I have the parser as a separate object, is it correct to alloc, init an instance of that parser & then tell RootViewController to make it's table data source a copy of the parser's array. I can't include code because I haven't written anything yet, I'm just trying to get the design right before I start. Perhaps something like: xmlParser = [[XMLParser alloc] init]; [xmlParser getXMLData]; // Assuming xmlParser stores results in an array called returnedArray self.tableDataSource = xmlParser.returnedArray Is this the best way of doing it?

  • Using pointers, references, handles to generic datatypes, as generic and flexible as possible

    - by Patrick
    In my application I have lots of different data types, e.g. Car, Bicycle, Person, ... (they're actually other data types, but this is just for the example). Since I also have quite some 'generic' code in my application, and the application was originally written in C, pointers to Car, Bicycle, Person, ... are often passed as void-pointers to these generic modules, together with an identification of the type, like this: Car myCar; ShowNiceDialog ((void *)&myCar, DATATYPE_CAR); The 'ShowNiceDialog' method now uses meta-information (functions that map DATATYPE_CAR to interfaces to get the actual data out of Car) to get information of the car, based on the given data type. That way, the generic logic only has to be written once, and not every time again for every new data type. Of course, in C++ you could make this much easier by using a common root class, like this class RootClass { public: string getName() const = 0; }; class Car : public RootClass { ... }; void ShowNiceDialog (RootClass *root); The problem is that in some cases, we don't want to store the data type in a class, but in a totally different format to save memory. In some cases we have hundreds of millions of instances that we need to manage in the application, and we don't want to make a full class for every instance. Suppose we have a data type with 2 characteristics: A quantity (double, 8 bytes) A boolean (1 byte) Although we only need 9 bytes to store this information, putting it in a class means that we need at least 16 bytes (because of the padding), and with the v-pointer we possibly even need 24 bytes. For hundreds of millions of instances, every byte counts (I have a 64-bit variant of the application and in some cases it needs 6 GB of memory). The void-pointer approach has the advantage that we can almost encode anything in a void-pointer and decide how to use it if we want information from it (use it as a real pointer, as an index, ...), but at the cost of type-safety. Templated solutions don't help since the generic logic forms quite a big part of the application, and we don't want to templatize all this. Additionally, the data model can be extended at run time, which also means that templates won't help. Are there better (and type-safer) ways to handle this than a void-pointer? Any references to frameworks, whitepapers, research material regarding this?

  • Dummy SMTP Server for testing apps that send email

    - by Patrick McElhaney
    I have a lot of apps that send email. Sometimes it's one or two messages at a time. Sometimes it's thousands of messages. In development, I usually test by substituting my own address for any recipient addresses. I'm sure that's what everybody else does, until they get fed up with it and find a better solution. I was thinking about creating a dummy SMTP server that just catches the messages and dumps them in a SQLLite database, or an mbox file, or whatever. But surely such a tool already exists? How do you test sending email?

  • How do I create a regular expression to match a word misspelling the original case sensitivity?

    - by Patrick Allaert
    I want to discover wrong spelling of "FooBar" in sentence: "This is a 'FooBar' example where I should match different spelling of fooBar such as: foobar, FOOBAR or even fOoBaR but not foobarS!" In this sentence, I would like to match words (in order): fooBar, foobar, FOOBAR, fOoBaR and not: FooBar (correct spelling), foobarS (not the same word) Is there an existing solution using Perl Regular Expression? This is intended to be used with grep -P Thanks

  • How to know why an animation stutters?

    - by Patrick Klug
    I have a few fairly simple animations (moving text around, moving ellipses etc.) and running in full screen (1920x1080 minus the task bar) the WPF Performance Suite reports a good framerate around 50 FPS throughout the animation. Dirty Rect Addition is somewhere around 300 rect/s, the SW frames are between 0 and 4 and the HW frames are between 3 and 5. Video memory usage is around 80 MB. Problem is that the animations stutters every other half second. My machine is a new Dell laptop XPS 15 with the GeForce GT 435 with 2GB memory. - The drivers are up to date. (The same behavior occurs on my netbook (in full screen) as well so I don't think it is hardware related.) If I make the window smaller the stutter goes away. The stutter occurs with the simplest of animations - even with just a couple of elements but adding more elements certainly makes it more noticeable. How can I find out what causes this stutter? When I think of it, I have not actually seen any WPF animations which run smoothly in full screen. Is this even possible?

  • database text field databound to a checkbox

    - by Patrick
    I'd like the field to save as a 1 or 0 instead of 'True' or 'False' in the database and i cannot figure out how to do it without manually setting every property when the record is saved. I have to use this a lot in this project and a bit field is not an option. I would like to solve this issue by extending the CheckBox control if possible but i don't know how to change the binding fields value. Any help would be greatly appreciated!

  • How to query the video ram size of a ATI card on Linux?

    - by Patrick Bao
    I want to know the physical video ram size in my application. I can get the same information of Nvidia card by using "nvidia-settings -q -t VideoRam". I can use amdcccle to find this information, but it's an GUI app, so can't be used in my application. I wonder if there is a way to get this by command, function, or config file? I'm using RHEL 5.4.

  • Objects With No Behavior

    - by Patrick Donovan
    I've been teaching myself object oriented programming and I'm thinking about a situation where I have an object "Transaction", that has quite a few properties to it like account, amount, date, currency, type, etc. I never plan to mutate these data points, and calculation logic will live in other classes. My question is, is it poor Python design to instantiate thousands of objects just to hold data? I find the data far easier to work with embedded in a class rather than trying to cram it into some combination of data structures.

  • Android google.navigation Intent Modes?

    - by Patrick Mahoney
    I'm currently developing an application that will launch a navigation intent. I know that this isn't an official API, but it works perfectly the way I want it to. I allow the user to select driving, walking, and bus navigation to a location. The intent to launch directly into Google Maps Navigation looks like this: google.navigation:ll= + a latitude and longitude, then + &mode= then your mode of transportation. For example, to navigate using walking directions to a certain area: google.navigation:ll=blah,blah&mode=w Driving is default, or &mode=d, and biking is &mode=b, but I can't figure out bus (public transit). Has anyone done this before? Thanks! Edit: So far, I've found that mode=public gives bike directions, mode=transit gives driving, frustratingly, mode=bus also returns bike directions.

  • php: problems with embedded apex in a string ?

    - by Patrick
    how can I write more embedded " and ' in php ? For example, I dunno how to write this html complete element with all apex: As you can see, I use '' for the php string. Then inside, I use "", but then I need another level of apix and I dunno how to write that one in my php document. (php thinks that the string is complete in the middle because it sees another ' before the end. $output .= '<img style="outline:none;" src="sites/default/unselect.png" alt="Unselect All" onclick='$(this).siblings('.form-item').each(function(index){ $('input:checkbox', this).attr('checked', ''); });'/>'; how can I solve this ? thanks

  • What is best practice about having one-many hibernate

    - by Patrick
    Hi all, I believe this is a common scenario. Say I have a one-many mapping in hibernate Category has many Item Category: @OneToMany( cascade = {CascadeType.ALL},fetch = FetchType.LAZY) @JoinColumn(name="category_id") @Cascade( value = org.hibernate.annotations.CascadeType.DELETE_ORPHAN ) private List<Item> items; Item: @ManyToOne(targetEntity=Category.class,fetch=FetchType.EAGER) @JoinColumn(name="category_id",insertable=false,updatable=false) private Category category; All works fine. I use Category to fully control Item's life cycle. But, when I am writing code to update Category, first I get Category out from DB. Then pass it to UI. User fill in altered values for Category and pass back. Here comes the problem. Because I only pass around Category information not Item. Therefore the Item collection will be empty. When I call saveOrUpdate, it will clean out all associations. Any suggestion on what's best to address this? I think the advantage of having Category controls Item is to easily main the order of Item and not to confuse bi-directly. But what about situation that you do want to just update Category it self? Load it first and merge? Thank you.

  • discover if mod_rewrite is working (MAMP + codeigniter)

    - by Patrick
    Hi, I'm experimenting (and having problems!) with codeigniter. In particular, links do not work. even if they are correct (eg. http://localhost/ci-book/welcome/cat/3, where welcome is controller, cat the method), they can't be open and chrome says "Oops! This link appears to be broken...." Someone suggested to check that mod_rewrite is working. How can I do that? I'm using Mamp. thanks, P.

  • What are the restrictions for the name of an application when submitting to App Store ?

    - by Patrick
    Hello, I have just finished my application for iPhone. I would like to know if it is possible to use the word iPhone in the name of the application. For example, can I name my application iPhonesque ? And for the icon, can I use graphics related to Apple like a Mac Windows (with the three buttons, red, yellow and green) on snow leopard background ? Thank you very much for your answers.
