/* TEMPLATE_FUNCTION_TABLE()
(Note added to platform.h so platforms that correctly support templated
functions can handle portions as templated functions rather than wrapped
functions)
Helps automate the process of creating an array of function
templates that are all specialized by a single integer.
This sort of thing is often useful in optimization work.
For example, using TEMPLATE_FUNCTION_TABLE, this:
TEMPLATE_FUNCTION_TABLE(int, Function, ( int blah, int blah ), 10)
{
return argument * argument;
}
is equivilent to the following:
(NOTE: the function has to be wrapped in a class due to code
generation bugs involved with directly specializing a function
based on a constant.)
template<int argument>
class FunctionWrapper
{
public:
int Function( int blah, int blah )
{
return argument*argument;
}
}
typedef int (*FunctionType)( int blah, int blah );
class FunctionName
{
public:
enum { count = 10 };
FunctionType functions[10];
};
