Detailed Description

template<class BinaryFunctor>
class eoBinaryFunctorCounter< BinaryFunctor >

Generic counter class that counts the number of times a binary function is used.

Add a binary function through its ctor and use this class instead of it.

It is derived from eoValueParam so you can add it to a monitor.

Member Function Documentation

template<class BinaryFunctor>

BinaryFunctor::result_type eoBinaryFunctorCounter< BinaryFunctor >::operator()	(	typename BinaryFunctor::first_argument_type	_arg1,
		typename BinaryFunctor::second_argument_type	_arg2
	)		[inline]

Calls the embedded function and increments the counter.

Note for MSVC users, if this code does not compile, you are quite likely trying to count a function that has a non-void return type. Don't look at us, look at the MSVC builders. Code like "return void;" is perfectly legal according to the ANSI standard, but the guys at Microsoft didn't get to implementing it yet.

We had two choices: assuming (and compiling ) code that returns void or code that returns non-void. Given that in EO most functors return void, it was chosen to support void.

But also please let me know if you have a compiler that defines _MSC_VER (lot's of windows compilers do), but is quite capable of compiling return void; type of code. We'll try to change the signature then.

You happy GNU (and other compiler) users will not have a problem with this.
