Changeset 7192 for code/branches/consolecommands3/src/libraries/core/Functor.h

Timestamp:

Message:

Added a small SharedPtr template for use in Functor and Executor. It's an intrusive approach that requires the object to implement a reference counter. The SharedPtr is extensible to reflect the hierarchy of Functor, FunctorStatic, FunctorMember<T>, and all subclasses (same for Executor).
