5,292,681 | 5,292,682 | What's your naming convention for the View IDs? | <p>I believe that many of us were bothered while naming the View IDs. Unlike the package mechanism, the IDs of the resources in a project are using one common namespace. Therefore, we have to figure out some ways to name the fields with the same functionality but in different layout files.</p>
<p>My way is to add the noun or the verb that the layout file's Acitvity class name used in the front of the original ID, separated by a dot. For example,an ID originally named "description" in a Activity displaying a movie's information may become "movie.details.description".</p>

1,851,910 | 1,851,911 | How to make "int" parse blank strings? | <p>I have a parsing system for fixed-length text records based on a layout table:</p>
<pre><code>parse_table = [\
('name', type, length),
....
('numeric_field', int, 10), # int example
('textc_field', str, 100), # string example
...
]
</code></pre>
<p>The idea is that given a table for a message type, I just go through the string, and reconstruct a dictionary out of it, according to entries in the table.</p>
<p>Now, I can handle strings and proper integers, but <code>int()</code> will not parse all-spaces fields (for a good reason, of course).</p>
<p>I wanted to handle it by defining a subclass of <code>int</code> that handles blank strings. This way I could go and change the type of appropriate table entries without introducing additional kludges in the parsing code (like filters), and it would "just work".</p>
<p>But I can't figure out how to override the constructor of a build-in type in a sub-type, as defining constructor in the subclass does not seem to help. I feel I'm missing something fundamental here about how Python built-in types work.</p>
<p>How should I approach this? I'm also open to alternatives that don't add too much complexity.</p>

4,185,363 | 4,185,364 | Typecasting method pointer to parent class method | <p>What i'm trying to do is somewhat obscure, so let me show on an example (this is not the actual code):</p>
<pre><code>template <class T>
class ArrayStorage {
protected:
void processStuff(void (ArrayStorage<T>::*procedure)(T *)) {
for (int i = 0; i < count; i++)
(this->*procedure)(content[i]);
}
// No method of type void (ArrayStorage<T>::*)(T *)
private:
T **content;
int count;
};
class DrawableStorage : public ArrayStorage<Drawable> {
public:
void drawStuff() {
processStuff((void (ArrayStorage<Drawable>::*)(Drawable *)) &DrawableStorage::drawOne);
}
private:
void drawOne(Drawable *item) {
item->draw();
}
};
</code></pre>
<p>Basically, there is a generic container that is able to iterate through its items and use a method on each of them (whose pointer is in the parameter). This method however does not exist in this class, but only in its subclasses. You can see that in the subclass "drawStuff" method, i supply a method pointer of the sublass, but typecasted as a method of the base class.</p>
<p>Suprisingly enough, this has successfully compiled and works just fine.</p>
<p>My question is, is it just a coincidence that my particular compiler was able to handle it while in fact it is completely invalid and i should get rid of it, or is it correct usage of method pointers?</p>
<p>Thank you.</p>
