3,068,102 | 3,068,103 | Is it important to explicitly declare properties in PHP? | <p>I have followed a tutorial to create a simple blog writing application in PHP and have modified the classes in this tutorial so that they have additional capabilities. Modifying this very bare bones app has given me a better understanding of how PHP works, however I have run across an interesting situation. </p>
<p>One of the classes in my project has about a half dozen class properties such as <code>public $id, public $author, public $post</code>. These properties are declared at the beginning of this class however I find that if I remove all but one of these properties the app still functions correctly. </p>
<p>Is it wrong to remove a property declaration such as <code>public $datePosted</code> from the beginning of a class if this class still assigns variables to this property like this: `$this->datePosted = $someVariableName;'</p>

2,809,202 | 2,809,203 | How can I change this code to make it work? | <p>I'm starting with Flask, and I'm having some problems with jQuery and (I think) Flask's templating system. What I wanted to do is very simple: I've included a <em>behavior.js</em> script in the layout master template <em>layout.html</em>, after the jQuery library. Its contents are:</p>
<pre><code>jQuery(document).ready(function() {
var events = $("#fake_grid td");
while(events.length > 0) {
$("#the_grid").append($("<tr/>").append(events.slice(0, 3)));
}
$("#fake_grid").remove();
});
</code></pre>
<p>When I try to execute this, my browser crashes, and I can't figure it out why and how to fix it. I've been thinking about jQuery doesn't loading properly or loading after my script, but I've checked with FireBug and everything in that matter works fine. I've tried replacing all that code with an alert() and that worked fine, too. I've tried including my .js in the child template <em>index.html</em>, in several different ways, but it wasn't that, for sure. Maybe it's something with the document readyness thing.</p>
<p>If it is something else, I'm unable to see it, and that's making me really anxious. So, any advice in what to do about this? What I'm doing wrong? Thanks in advance.</p>

<p>Is that even possible?</p>

5,555,739 | 5,555,740 | Assigning a function (which is assigned dynamically) along with specific parameters, to a variable. | <p>Ok, so here's the deal, say I have a function( take_action ), that calls another function. But we don't know which function take_action is going to call.</p>
<p>I had that part figured out thanks to <a href="http://stackoverflow.com/questions/4246000/python-calling-functions-dynamically">this question</a>, the thing is, on that question they deal with functions that take no arguments, my take_action could take one of several different functions that are quite different from each other, with completely different actions taken, different arguments.</p>
<p>Now for some example code:</p>
<pre><code>def take_action():
action['action']()
#does other stuff with 'other_stuff_in_the_dic'
def move(x,y):
#stuff happens
action = {'action': move, 'other_stuff_in_the_dic': 'stuff' }
</code></pre>
<p>(In this case the 'action' would be move, but like I said, that's assigned dynamically depending on certain user input)</p>
<p>What I would like to do, is something like this:</p>
<pre><code>action = { 'action': move(2,3), 'other_stuff': 'stuff' }
</code></pre>
<p>(Obviously that calls the function there, since it has the (), hence it wouldn't work)</p>
<p>I'm only a beginner programmer, and the only thing I thought of is using a list, which is in another key inside the dic, but that would just pass one list argument, instead of each content of the list being passed on as an argument.</p>
<p>What would be a way to achieve this, so the 'action' key (or the dictionary on another key?) also stores the arguments it should use when I call it on take_action?</p>

Here is the link to the OpenCV library: <a href="http://code.opencv.org/projects/opencv/wiki/OpenCV4Android" rel="nofollow">http://code.opencv.org/projects/opencv/wiki/OpenCV4Android</a> And here is a link to the issue report: <a href="http://code.opencv.org/issues/1244" rel="nofollow">http://code.opencv.org/issues/1244</a> The issue report lists the target version for the fix to be 2.5 (currently at 2.4). Does anyone have any first hand experience with these issues and any workarounds for the current version of the library? From the OpenCV Google Group there seems to be some discussion about using the "Java Camera" instead of the "OpenCV native" camera. I'm not sure what they mean by this. Thanks for the help! --amb</p>

2,184,117 | 2,184,118 | C# Getting an object's actual TypeDescriptionProvider or TypeDescriptor | <p>I realise that this is an unusual issue, but:</p>
<p>I have created a custom TypeDescriptionProvider that can store and return different <code>TypeDescriptors</code> based on the requested object Type. What I have noticed however is that regardless of the <code>TypeDescriptionProvider</code> associated with a Type (be-it custom or default) the <code>TypeDescriptor.GetProvider()</code> always returns an (internal class) <code>System.ComponentModel.TypeDescriptor.TypeDescriptionNode</code> object (some kind of wrapper around the actual <code>TypeDescriptionProvider</code>). In turn calling <code>GetTypeDescriptor()</code> on this object always returns a <code>System.ComponentModel.TypeDescriptor.TypeDescriptionNode.DefaultTypeDescriptor</code> object (another wrapper) and stranger still does not call the <code>TypeDescriptionProvider</code>'s actual <code>GetTypeDescriptor()</code> method.</p>
<p>Does this mean that there is really no way to get back either an object's actual <code>TypeDescriptionProvider</code> or its <code>TypeDescriptor</code> from its provider? The methods to return the classname, properties, etc. still work as expected on the <code>DefaultTypeDescriptor</code>, but I am unable to compare or find out if two objects use the same <code>TypeDescriptor</code> (which is what I need currently). </p>
<p>Does anyone know how to either get the actual <code>TypeDescriptionProvider</code>, or get the actual TypeDescriptor from the wrapped provider? </p>
<p>Thank you in advance.</p>
<p>Ex:</p>
<pre><code>public class TestTypeDescriptionProvider : TypeDescriptionProvider
{
private static Dictionary<Type, ICustomTypeDescriptor> _descriptors = new Dictionary<Type, ICustomTypeDescriptor>();
...static method to add to the cache...
public override ICustomTypeDescriptor GetTypeDescriptor(Type objectType, object instance)
{
if (objectType == null)
return _descriptors[instance.GetType()];
return _descriptors[objectType];
}
}
...
TypeDescriptionProvider p = TypeDescriptor.GetProvider(obj.GetType()); //p is a TypeDescriptionNode
ICustomTypeDescriptor td = p.GetTypeDescriptor(obj); // td is a DefaultTypeDescriptor

4,263,917 | 4,263,918 | Vector of Vector of (member) function pointers | <p>I'm constructing an simple listener / callback mechanism, for my current experimental project. And i'm stuck with implementing a container structure what seems should be vector of vector of pointers. I choose this way because i want the root vector to simple have KEY of event type let's say is an enum (int), then at this key i want to store vector of pointers to available methods for this event type. In logical representation something like:</p>
<pre><code>[EVENT_TYPE_QUIT]
[ptr1]
[ptr2]
[ptr3]
[ptr4]
[....]
[EVENT_TYPE_HELLO]
[....]
[....]
typedef enum {
EVENT_TYPE_QUIT,
EVENT_TYPE_HELLO,
...
} EventType;
</code></pre>
<p>So the simplified implementation looks something like this (it's an template in reality but imagine T is any user type you can map an event).</p>
<pre><code>class EventMapper {
...
typedef void (T::*functionPtr)(); // simple pointer to T member function with no args.
std::vector< std::vector<functionPtr> > eventCallbacks;
void mapEvent(const EventType type, functionPtr callback) {
// here i need to map type to callback
// each type can have multiple callbacks
// T can have only distinct event types as "key"
// this i tried but doesn't work
eventCallbacks[type].push_back(callback);
}
...
}
</code></pre>
<p>The intended implementation would look something like:</p>
<pre><code>EventMapper<SupaDupaClass> mapper;
mapper.mapEvent(EVENT_TYPE_HELLO, &SupaDupaClass::didYouSayHello);
</code></pre>
<p>etc ... </p>
<p>I really would like to use vector instead of map for easier unique key assignment ?
