\doxysubsection{Detailed Description}
\subsubsection*{template$<$class Unary\+Functor$>$\newline
class eo\+Unary\+Functor\+Counter$<$ Unary\+Functor $>$}

\begin{DoxyVerb}  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.
\end{DoxyVerb}


It is derived from \mbox{\hyperlink{classeo_value_param}{eo\+Value\+Param}} so you can add it to a monitor.

Example\+: suppose you have an \mbox{\hyperlink{classeo_eval_func}{eo\+Eval\+Func}} called myeval, to count the number of evaluations, just define\+:

eo\+Unary\+Functor\+Counter$<$void, Eo\+Type$>$ eval\+Counter(myeval);

and use eval\+Counter now instead of myeval.

Calls the embedded function and increments the counter

Note for M\+S\+VC users, if this code does not compile, you are quite likely trying to count a function that has a non-\/void return type. Don\textquotesingle{}t look at us, look at the M\+S\+VC builders. Code like \char`\"{}return void;\char`\"{} is perfectly legal according to the A\+N\+SI standard, but the guys at Microsoft didn\textquotesingle{}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 \mbox{\hyperlink{class_e_o}{EO}} most functors return void, it was chosen to support void.

But also please let me know if you have a compiler that defines \+\_\+\+M\+S\+C\+\_\+\+V\+ER (lot\textquotesingle{}s of windows compilers do), but is quite capable of compiling return void; type of code. We\textquotesingle{}ll try to change the signature then.

You happy G\+NU (and other compiler) users will not have a problem with this. \mbox{\Hypertarget{classeo_unary_functor_counter_a793a3b2cf3a3d7f8b46c8e16960be996}\label{classeo_unary_functor_counter_a793a3b2cf3a3d7f8b46c8e16960be996}}
