## NAME

ACE_Hash_Map_Manager - Wrapper for backward compatibility.

## SYNOPSIS

    #include <ace/Hash_Map_Manager_T.h>

    template<class EXT_ID, class INT_ID, class ACE_LOCK>
    class ACE_Hash_Map_Manager :
      public ACE_Hash_Map_Manager_Ex<EXT_ID, INT_ID, ACE_Hash<EXT_ID>, ACE_Equal_To<EXT_ID>, ACE_LOCK>
    {
      public:
        ACE_Hash_Map_Manager (ACE_Allocator *alloc = 0);
        ACE_Hash_Map_Manager (size_t size, ACE_Allocator *alloc = 0);
        int equal (const EXT_ID &id1, const EXT_ID &id2);
        u_long hash (const EXT_ID &ext_id);
    };

## DESCRIPTION

This implementation of a map uses a hash table. This class expects that the `EXT_ID` contains a method called `hash`. In addition, the `EXT_ID` must support `operator==`. Both of these constraints can be alleviated via template specialization, as shown in the $ACE_ROOT/tests/Conn_Test.cpp test.

## The following two are necessary for template specialization of

ACE_Hash_Map_Manager to work.

    int equal (const EXT_ID &id1, const EXT_ID &id2);

    u_long hash (const EXT_ID &ext_id);
