I have a question about assigning __call__ to an instance to make that
instance callable. I know there has been quite a bit of discussion
about this, and I've read all I can find, but I'm still confused.
I'd like to have a factory class that takes a string argument and returns
the appropriate factory method based on that string. I'd like...

Hi all!
I'm posting to both newsgroups, because it's actually a C++ problem but
could be that some of you using Matlab-&-MEX-&-C++ was struggling with the

algebra I want to use the Matrix...

Hi, all.
When reading C++ books, I'm alway confused by those terms "redefining
functions", "overloading functions" and "overriding functions".
Please give me some comments on those terms. Thanks.
If giving more strategy hehind them, more helpful.
Best Regards,

Hi,
I know it is possible to refine operators (like +, -, * or /) on classes.
But is it possible on simple types ?
ex :
If I have a type like :
typedef int vector
is it possible to redefine a + operator on the vetor type ?
Thanks !

I'm planning to create a macro-based property system (reflection,
automatic serializing for properties, that kind of stuff). The system
would involve writing some PROPERTY(propName) macros between a
BEGIN_CLASS(ThisClass) and an END_CLASS() macro. The PROPERTY macros
should somehow know ThisClass, and that's where it start to get tricky.

How can I reuse an object that is already defined. I want to delete some files using the FileInfo class and the "name" is a read only property so I can't set the name as I want to. I don't want to delete all the files only a few of them in different Directories
For example this gives me an error. Is there a way to reset "FI" in this case......

the value of __FILE__ in a char*. Since gcc4.2 I get the following
warning...

used to track where deletions were made. Something like:

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it. ...
