  • Using memcpy/memset

    - by Andrew Coad
    When using memset or memcpy within an Obj-C program, will the compiler optimise the setting (memset) or copying (memcpy) of data into 32-bit writes or will it do it byte by byte?

  • Anyone familiar with CurvyCorners JS?

    - by Kyle Sevenoaks
    I am trying to implement the CurvyCorners script onto the site: euroworker.no. It reports back that certain CSS values don't exist on the page, how I can I turn off this alert? Found the alert code: if (j === null) curvyCorners.alert("No object with ID " + arg + " exists yet.\nCall curvyCorners(settings, obj) when it is created.");

  • What JavaScript object copy function works with greasemonkey?

    - by Geo
    I know there is another question related to copying objects in JavaScript here, but the code they provide does not work with greasemonkey. From what I was able to trace, the code for the accepted answer dies/ stops at the line : var temp = new obj.constructor(); Is there any way to see what went wrong ? It's not really necessary I use the same function for the object copying, but I would like something that works. Do you know some function?

  • Port Flash to iPhone

    - by LaGrad
    How hard would it be to port a flash game to the iPhone. Obviously Flash CS5 is no longer an options, I still would like to know if there's anything that can be reused? or do I have to write everything from scratch (Is Obj-C that different than ActionScript?) Is there any other shortcuts? Also, if anyone has done this before please share your experience.

  • Java: omitting a data member from the equals method.

    - by cchampion
    public class GamePiece { public GamePiece(char cLetter, int nPointValue) { m_cLetter=cLetter; m_nPointValue=nPointValue; m_nTurnPlaced=0; //has not been placed on game board yet. } public char GetLetter() {return m_cLetter;} public int GetPointValue() {return m_nPointValue;} public int GetTurnPlaced() {return m_nTurnPlaced;} public void SetTurnPlaced(int nTurnPlaced) { m_nTurnPlaced=nTurnPlaced; } @Override public boolean equals(Object obj) { /*NOTE to keep this shorter I omitted some of the null checking and instanceof stuff. */ GamePiece other = (GamePiece) obj; //not case sensitive, and I don`t think we want it to be here. if(m_cLetter != other.m_cLetter) { return false; } if(m_nPointValue != other.m_nPointValue) { return false; } /* NOTICE! m_nPointValue purposely omitted. It does not affect hashcode or equals */ return true; } @Override public int hashCode() { /* NOTICE! m_nPointValue purposely omitted. It should not affect hashcode or equals */ final int prime = 41; return prime * (prime + m_nPointValue + m_cLetter); } private char m_cLetter; private int m_nPointValue; private int m_nTurnPlaced;//turn which the game piece was placed on the game board. Does not affect equals or has code! } Consider the given piece of code. This object has been immutable until the introduction of the m_nTurnPlaced member (which can be modified by the SetTurnPlaced method, so now GamePiece becomes mutable). GamePiece is used in an ArrayList, I call contains and remove methods which both rely on the equals method to be implemented. My question is this, is it ok or common practice in Java for some members to not affect equals and hashcode? How will this affect its use in my ArrayList? What type of java Collections would it NOT be safe to use this object now that it is mutable? I've been told that you're not supposed to override equals on mutable objects because it causes some collections to behave "strangely" (I read that somewhere in the java documentation).

  • error loading (TypeLoadException) on asp.net/xsp/mono on debian/opensuse

    - by acidzombie24
    When i reset apache and load my website i get the first error below. I have no idea what the problem is. If i reload the page again (without restarting apache) i get the 2nd error, probably because the first error occurred and BaseUser is the first class/func that Application_Start uses. Why am i getting this load exception? Whats messed up is i tried using mono's VMWare img to debug it and i got the very same exception (until i restarted which now refuses to give me anything but 404 errors). However when i use mono develop to run the project the site runs PERFECT. WTF. Any ideas? Server Error in '/' Application A type load exception has occurred. Description: HTTP 500. Error processing request. Stack Trace: System.TypeLoadException: A type load exception has occurred. at (wrapper managed-to-native) System.Reflection.MonoMethod:InternalInvoke (System.Reflection.MonoMethod*,object,object[],System.Exception&) at System.Reflection.MonoMethod.Invoke (System.Object obj, BindingFlags invokeAttr, System.Reflection.Binder binder, System.Object[] parameters, System.Globalization.CultureInfo culture) [0x00000] in <filename unknown>:0 Version information: Mono Runtime Version: 2.8.1 (tarball Mon Dec 27 10:20:03 UTC 2010); ASP.NET Version: 2.0.50727.1433 Second: Server Error in '/' Application Could not load type 'mynamespace.BaseUser' from assembly 'mynamespace, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.

  • C# - Dynamic Keyword and Interface Implementations

    - by Adam Driscoll
    I'm assuming this isn't possible but before digging further is there a way to do something like this: public void ProcessInterface(ISomeInterface obj) {} //... dynamic myDyn = GetDynamic<ISomeInterface>() ProcessInterface(myDyn); I've seen a post arguing for it but it sounds like it wasn't included. A little context: .Net assembly exposed through COM - Silverlight app consuming interface-implementing classes. Would be nice to refer to the objects by interface. I really don't expect that this was what was intended...

  • How do I add a trailing slash for Django MPTT-based categorization app?

    - by Patrick Beeson
    I'm using Django-MPTT to develop a categorization app for my Django project. But I can't seem to get the regex pattern for adding a trailing slash that doesn't also break on child categories. Here's an example URL: http://mydjangoapp.com/categories/parentcat/childcat/ I'd like to be able to use http://mydjangoapp.com/categories/parentcat and have it redirect to the trailing slash version. The same should apply to http://mydjangoapp.com/categories/parentcat/childcat (it should redirect to http://mydjangoapp.com/categories/parentcat/childcat/). Here's my urls.py: from django.conf.urls.defaults import patterns, include, url from django.views.decorators.cache import cache_page from storefront.categories.models import Category from storefront.categories.views import SimpleCategoryView urlpatterns = patterns('', url(r'^(?P<full_slug>[-\w/]+)', cache_page(SimpleCategoryView.as_view(), 60 * 15), name='category_view'), ) And here is my view: from django.core.exceptions import ImproperlyConfigured from django.core.urlresolvers import reverse from django.views.generic import TemplateView, DetailView from django.views.generic.detail import SingleObjectTemplateResponseMixin, SingleObjectMixin from django.utils.translation import ugettext as _ from django.contrib.syndication.views import Feed from storefront.categories.models import Category class SimpleCategoryView(TemplateView): def get_category(self): return Category.objects.get(full_slug=self.kwargs['full_slug']) def get_context_data(self, **kwargs): context = super(SimpleCategoryView, self).get_context_data(**kwargs) context["category"] = self.get_category() return context def get_template_names(self): if self.get_category().template_name: return [self.get_category().template_name] else: return ['categories/category_detail.html'] And finally, my model: from django.db import models from mptt.models import MPTTModel from mptt.fields import TreeForeignKey class CategoryManager(models.Manager): def get(self, **kwargs): defaults = {} defaults.update(kwargs) if 'full_slug' in defaults: if defaults['full_slug'] and defaults['full_slug'][-1] != "/": defaults['full_slug'] += "/" return super(CategoryManager, self).get(**defaults) class Category(MPTTModel): title = models.CharField(max_length=255) description = models.TextField(blank=True, help_text='Please use <a href="http://daringfireball.net/projects/markdown/syntax">Markdown syntax</a> for all text-formatting and links.

  • How can i convert this to a factory/abstract factory?

    - by Amitd
    I'm using MigraDoc to create a pdf document. I have business entities similar to the those used in MigraDoc. public class Page{ public List<PageContent> Content { get; set; } } public abstract class PageContent { public int Width { get; set; } public int Height { get; set; } public Margin Margin { get; set; } } public class Paragraph : PageContent{ public string Text { get; set; } } public class Table : PageContent{ public int Rows { get; set; } public int Columns { get; set; } //.... more } In my business logic, there are rendering classes for each type public interface IPdfRenderer<T> { T Render(MigraDoc.DocumentObjectModel.Section s); } class ParagraphRenderer : IPdfRenderer<MigraDoc.DocumentObjectModel.Paragraph> { BusinessEntities.PDF.Paragraph paragraph; public ParagraphRenderer(BusinessEntities.PDF.Paragraph p) { paragraph = p; } public MigraDoc.DocumentObjectModel.Paragraph Render(MigraDoc.DocumentObjectModel.Section s) { var paragraph = s.AddParagraph(); // add text from paragraph etc return paragraph; } } public class TableRenderer : IPdfRenderer<MigraDoc.DocumentObjectModel.Tables.Table> { BusinessEntities.PDF.Table table; public TableRenderer(BusinessEntities.PDF.Table t) { table =t; } public MigraDoc.DocumentObjectModel.Tables.Table Render(Section obj) { var table = obj.AddTable(); //fill table based on table } } I want to create a PDF page as : var document = new Document(); var section = document.AddSection();// section is a page in pdf var page = GetPage(1); // get a page from business classes foreach (var content in page.Content) { //var renderer = createRenderer(content); // // get Renderer based on Business type ?? // renderer.Render(section) } For createRenderer() i can use switch case/dictionary and return type. How can i get/create the renderer generically based on type ? How can I use factory or abstract factory here? Or which design pattern better suits this problem?

  • javascript simple object creation test: opera leaks?

    - by joe
    Hi, I am trying to figure out certain memory leak conditions in javascript on a few browsers. Currently I'm only testing FF 3.6, Opera 10.10, and Safari 4.0.3. I've started with a fairly simple test, and can confirm no memory leaks in Firefox and Safari. But Opera just takes memory and never gives it back. What gives? Here's the test: <html> <head> <script type="text/javascript"> window.onload = init; //window.onunload = cleanup; var a=[]; function init() { var d = document.createElement('div'); d.innerHTML = "page loading..."; document.body.appendChild(d); for (var i=0; i<400000; i++) { a[i] = new Obj("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"); } d.innerHTML = "PAGE LOADED"; } function cleanup() { for (var i=0; i<400000; i++) { a[i] = null; } } function Obj(msg) { this.msg=msg; } </script> </head> <body> </body> </html> I shouldn't need the cleanup() call on window.unload, but tried that also. No luck. As you can see this is simple JS, no circular DOM links, no closures. I monitor the memory usage using 'top' on Mac 10.4.11. Memory usage spikes up on page load, as expected. In FF and Safari reloading the page does not use any further memory, and all memory is returned when the window (tab) is closed. In Opera, memory spikes on load, and seems to also spike further on each reload (but not always...). But regardless of reload, memory never goes back down below the initial load spike. I had hoped this was a no-brainer test that all browsers would pass, so I could move on to more "interesting" conditions. Am I doing something wrong here? Or is this a known Opera issue? Thanks! -joe

  • ProgressDialog does not disappear after executing dismiss, hide or cancel?

    - by Martin
    Hello, I have an Overlay extension which has 2 dialogs as private attributes - one Dialog and one ProgressDialog. After clicking on the Overlay in the MapView, the Dialog object appears. When the user clicks a button in the Dialog it disappears and the ProgressDialog is shown. Simultaneously a background task is started by notifying a running Service. When the task is done, a method (buildingLoaded) in the Overlay object is called to switch the View and to dismiss the ProgressDialog. The View is being switched, the code is being run (I checked with the debugger) but the ProgressDialog is not dismissed. I also tried hide() and cancel() methods, but nothing works. Can somebody help me? Android version is 2.2 Here is the code: public class LODOverlay extends Overlay implements OnClickListener { private Dialog overlayDialog; private ProgressDialog progressDialog; .............. @Override public void onClick(View view) { ....... final Context ctx = view.getContext(); this.progressDialog = new ProgressDialog(ctx); ListView lv = new ListView(ctx); ArrayAdapter<String> adapter = new ArrayAdapter<String>(ctx, R.layout.layerlist, names); lv.setAdapter(adapter); final LODOverlay obj = this; lv.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View view, int position, long id) { String name = ((TextView) view).getText().toString(); Intent getFloorIntent = new Intent(Map.RENDERER); getFloorIntent.putExtra("type", "onGetBuildingLayer"); getFloorIntent.putExtra("id", name); view.getContext().sendBroadcast(getFloorIntent); overlayDialog.dismiss(); obj.waitingForLayer = name; progressDialog.show(ctx, "Loading...", "Wait!!!"); } }); ....... } public void buildingLoaded(String id) { if (null != this.progressDialog) { if (id.equals(this.waitingForLayer)) { this.progressDialog.hide(); this.progressDialog.dismiss(); ............ Map.flipper.showNext(); // changes the view } } } }

  • Entities equals(), hashCode() and toString(). How to correctly implement them?

    - by spike07
    I'm implementing equals(), hashCode() and toString() of my entities using all the available fields in the bean. I'm getting some Lazy init Exception on the frontend when I try to compare the equality or when I print the obj state. That's because some list in the entity can be lazy initialized. I'm wondering what's the correct way to for implementing equals() and toString() on an entity object.

  • Jquery $().each method obscures 'this' keyword

    I am creating a Javascript object that contains a function that executes a jQuery each method like the following: function MyClass { Method1 = function(obj) { // Does something here } Method2 = function() { $(".SomeClass").each(function() { // 1 2 this.Method1(this); }); } } Which object is each THIS referring to? jQuery is referring to the item returned from the each iteration. However, I would like This[1] to refer to the containing class... How can I refer to the containing class from within the jQuery loop?
