This methods synchronizes the assignment with the getLocked() operation and thereby makes sure that a client can always get a valid, locked buffer object.

The calling instance is responsible for unlocking the buffer as soon as it is no longer used. Note: testing for NULL is suggested since getLocked() might return NULL, if no buffer of NULL was assigned! Definition at line 147 of file State.cxx.
