source: code/branches/consolecommands3/src/libraries/core/Functor.h @ 7196

Last change on this file since 7196 was 7196, checked in by landauf, 14 years ago

Changed implementation of SharedPtr, it's now non-intrusive and uses an allocated counter instead. Hence it's possible to create an instance of SharedPtr<T> even if T is only known from a forward declaration. Also changed some parts of the code to reflect the inheritance of the underlying object pointers without using inheritance in the SharedPtr itself.
