plist::PrimitiveBase Class Reference
#include <plistBase.h>
Inheritance diagram for plist::PrimitiveBase:
Detailed Description
Provides common functionality to all primitive value classes (implemented in a templated subclass Primitive).This class supports callbacks upon modification through the use of the PrimitiveListener interface. Note that we only store a pointer to the listener list, which is typically unallocated when no listeners are active. This should ensure minimal memory usage per object, as well as support safe storage of plist objects in inter-process shared memory regions.
If you are using these in a shared memory region, just be sure that only the process with listeners does any and all modifications, and that it unsubscribes before detaching from the region (or else destroys the region itself)
