Documentation

Class for adapting the memory management of external data. Typically used to specify the memory management of user data which can be attached to osg::Node.

MemoryAdapter()

virtual void ref_data(void* ) = 0

Increment the reference count of the userData

virtual void unref_data(void* ) = 0

Decrement the reference count of the userData. Is usually implemented such that if reference count is decremented to zero the userData should be deleted. However, this is entirely up to the discression of the user who is extending this base class.

virtual void* clone_data(void* )

not current used, but will be used in future

virtual ~MemoryAdapter()
