public abstract class ByReference extends PointerType
Provides generic "pointer to type" functionality, often used in C code to return values to the caller in addition to a function result.Derived classes must define
setValue(<T>)and<T> getValue()methods which write to/read from the allocated memory.This class derives from PointerType instead of Memory in order to restrict the API to only
getValue/setValue.NOTE: this class would ideally be replaced by a generic.
