Member predicate FunctionOutput::isReturnValue

Holds if this is the value returned by a function.

Example:

int getInt();
char* getPointer();
float& getReference();
  • isReturnValue() holds for the FunctionOutput that represents the value returned by getInt() (with type int).
  • isReturnValue() holds for the FunctionOutput that represents the value returned by getPointer() (with type char*).
  • isReturnValue() holds for the FunctionOutput that represents the “value” of the reference returned by getReference() (with type float&), not the value of the referred-to float.
