.SS "template<class UnaryFunctor> class eoUnaryFunctorCounter< UnaryFunctor >"
Generic counter class that counts the number of times a unary function is used. 

Add a unary function through its ctor and use this class instead of it.
.PP
It is derived from \fBeoValueParam\fP so you can add it to a monitor.
.PP
Example: suppose you have an \fBeoEvalFunc\fP called myeval, to count the number of evaluations, just define:
.PP
eoUnaryFunctorCounter<void, EoType> evalCounter(myeval);
.PP
and use evalCounter now instead of myeval.

.PP
Calls the embedded function and increments the counter. 
.PP
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.
.PP
We had two choices: assuming (and compiling ) code that returns void or code that returns non-void. Given that in \fBEO\fP most functors return void, it was chosen to support void.
.PP
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.
.PP
You happy GNU (and other compiler) users will not have a problem with this.
