Template of ingredient class

[caduel]

You declare a template... this makes the compiler happy.
But at link time, the calls can't be resolved as those functions have not been implemented (only called):
You have to tell the compiler that a specialization for int has to be compiled.

possible way to do it:
add

template<> void Pattern::function(int a) 
{ 
//code
}

template<> void Pattern::function(int a) 
{ 
//code
}

To copy to clipboard, switch view to plain text mode 

to class.cpp

or just leave the implementation in class.hpp and save you the trouble.
(putting specializations into the .cpp will reduce code bloat, though.)

So, when i want use my function like:

double a;
patternClass.function(a);

double a;
patternClass.function(a);

To copy to clipboard, switch view to plain text mode 

Must I define new function with argument double? If it's true, I can glut function with the same result.
