Member predicate FunctionInput::isParameter

Holds if this is the input value of the parameter with index index.

Example:

void func(int n, char* p, float& r);

• isParameter(0) holds for the FunctionInput that represents the value of n (with type int) on entry to the function.
• isParameter(1) holds for the FunctionInput that represents the value of p (with type char*) on entry to the function.
• isParameter(2) holds for the FunctionInput that represents the “value” of the reference r (with type float&) on entry to the function, not the value of the referred-to float.
