Detailed Description

template<class EXT_ID, class INT_ID>
class ACE_Hash_Map_With_Allocator< EXT_ID, INT_ID >

This class is a thin wrapper around ACE_Hash_Map_Manager, which comes handy when ACE_Hash_Map_Manager is to be used with a non-nil ACE_Allocator. This wrapper insures that the appropriate allocator is in place for every operation that accesses or updates the hash map.

If we use ACE_Hash_Map_Manager with a shared memory allocator (or memory-mapped file allocator, for example), the allocator pointer used by ACE_Hash_Map_Manager gets stored with it, in shared memory (or memory-mapped file). Naturally, this will cause horrible problems, since only the first process to set that pointer will be guaranteed the address of the allocator is meaningful! That is why we need this wrapper, which insures that appropriate allocator pointer is in place for each call.

At some point it would be a good idea to update this class to use the new "two allocator" technique provided by ACE_Hash_Map_Manager_Ex.
