 * @brief
 * Define a map abstraction that associates EXT_IDs with
 * INT_IDs.
 *
 * The EXT_ID must support @c operator==.  This constraint can
 * be alleviated via template specialization, as shown in the
 * $ACE_ROOT/tests/Conn_Test.cpp test.
 * This class uses an ACE_Allocator to allocate memory.  The
 * user can make this a persistant class by providing an
 * ACE_Allocator with a persistable memory pool.
 * This implementation of a map uses an array, which is searched
 * linearly.  For more efficient searching you should use the
 * ACE_Hash_Map_Manager.
