I developed a scripting engine that has many built-in functions, so to call any function, my code just went into an
if .. else if .. else if wall checking the name but I would like to develop a more efficient solution.
Should I use a hashmap with strings as keys and pointers as values? How could I do it by using an STL map?
EDIT: Another point that came into my mind: of course using a map will force the compiler not to inline functions, but my inefficient approach didn't have any overhead generated by the necessity of function calls, it just executes code.
So I wonder if the overhead generated by the function call will be any better than having an
if..else chain.. otherwise I could minimize the number of comparisons by checking a character at runtime (will be longer but faster).
