Provides a class that models parameters to functions.

Classes

FunctionInput	An input to a function. This can be: - The value of one of the function’s parameters - The value pointed to by one of function’s pointer or reference parameters - The value of the function’s `this` pointer - The value pointed to by the function’s `this` pointer
FunctionOutput	An output from a function. This can be: - The value pointed to by one of function’s pointer or reference parameters - The value pointed to by the function’s `this` pointer - The function’s return value - The value pointed to by the function’s return value, if the return value is a pointer or reference
InParameter	The input value of a parameter.
InParameterDeref	The input value pointed to by a pointer parameter to a function, or the input value referred to by a reference parameter to a function.
InQualifierAddress	The input value of the `this` pointer of an instance member function.
InQualifierObject	The input value pointed to by the `this` pointer of an instance member function.
InReturnValueDeref	The input value pointed to by the return value of a function, if the function returns a pointer, or the input value referred to by the return value of a function, if the function returns a reference.
OutParameterDeref	The output value pointed to by a pointer parameter to a function, or the output value referred to by a reference parameter to a function.
OutQualifierObject	The output value pointed to by the `this` pointer of an instance member function.
OutReturnValue	The value returned by a function.
OutReturnValueDeref	The output value pointed to by the return value of a function, if the function returns a pointer, or the output value referred to by the return value of a function, if the function returns a reference.
