Detailed Description

template<class EXT_ID, class INT_ID, class ACE_LOCK>
class ACE_Hash_Map_Manager< EXT_ID, INT_ID, ACE_LOCK >

Wrapper for backward compatibility.

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.

Requirements and Performance Characteristics

• Internal Structure Hash Table
• Duplicates allowed? No
• Random access allowed? Yes
• Search speed O(1)
• Insert/replace speed O(1), can be longer if the hash map has to resize
• Iterator still valid after change to container? Yes
• Frees memory for removed elements? Yes
• Items inserted by Value
• Requirements for key type
  1. Default constructor
  2. Copy constructor
  3. operator=
  4. operator==
• Requirements for object type
  1. Default constructor
  2. Copy constructor
  3. operator=
  4. operator<

Constructor & Destructor Documentation

template<class EXT_ID, class INT_ID, class ACE_LOCK>

ACE_Hash_Map_Manager< EXT_ID, INT_ID, ACE_LOCK >::ACE_Hash_Map_Manager

(

ACE_Allocator *

alloc = 0

)

Initialize a <Hash_Map_Manager> with default size.

template<class EXT_ID, class INT_ID, class ACE_LOCK>

ACE_Hash_Map_Manager< EXT_ID, INT_ID, ACE_LOCK >::ACE_Hash_Map_Manager	(	size_t	size,
		ACE_Allocator *	alloc = 0
	)

Initialize a <Hash_Map_Manager> with size <length>.

Member Function Documentation

template<class EXT_ID, class INT_ID, class ACE_LOCK>

int ACE_Hash_Map_Manager< EXT_ID, INT_ID, ACE_LOCK >::equal	(	const EXT_ID &	id1,
		const EXT_ID &	id2
	)

Returns 1 if <id1> == <id2>, else 0. This is defined as a separate method to facilitate template specialization.

Reimplemented from ACE_Hash_Map_Manager_Ex< EXT_ID, INT_ID, ACE_Hash< EXT_ID >, ACE_Equal_To< EXT_ID >, ACE_LOCK >.

template<class EXT_ID, class INT_ID, class ACE_LOCK>

u_long ACE_Hash_Map_Manager< EXT_ID, INT_ID, ACE_LOCK >::hash

(

const EXT_ID &

ext_id

)

Compute the hash value of the <ext_id>. This is defined as a separate method to facilitate template specialization.

Reimplemented from ACE_Hash_Map_Manager_Ex< EXT_ID, INT_ID, ACE_Hash< EXT_ID >, ACE_Equal_To< EXT_ID >, ACE_LOCK >.
