StrongACOWRefHandler Class Reference

#include <baseref.h>

Inheritance diagram for StrongACOWRefHandler:

Detailed Description

StrongACOWRefHandler has to be used as template argument for BaseRef to obtain a reference to objects which support reference counting, and which shall have always-copy-on-write semantics. This is similar to the copy-on-write semantics of StrongCOWRefHandler, but it also makes a copy if the reference to the pointee is exclusive. If the allocation of a copy fails the reference will be set to null.

Parameters

[in]

resetOnError

If true (the default), the reference will be reset when the copy fails. If false, the reference will stay the same, but the function returns nullptr.
