HASH_MAP & | map (void)
| Get a reference to the underlying hash map.
size_t | total_size (void)
| Return the size of the underlying hash table.

## Detailed Description

Provides hash-table-based transient storage for name to object bindings in a Naming Context.

A thin wrapper on top of ACE_Hash_Map_Manager. Supports TAO_Bindings_Map interface. Used by TAO_Transient_Naming_Context.

## Member Typedef Documentation

typedef ACE_Hash_Map_Manager<TAO_ExtId, TAO_IntId, ACE_Null_Mutex> TAO_Transient_Bindings_Map::HASH_MAP

| Underlying data structure - typedef for ease of use.

## Constructor & Destructor Documentation

TAO_Transient_Bindings_Map::TAO_Transient_Bindings_Map | ( | size_t | hash_table_size | ) |

| Constructor.

TAO_Transient_Bindings_Map::~TAO_Transient_Bindings_Map | ( | void |  | ) | `[virtual]`

| Destructor.

## Member Function Documentation

int TAO_Transient_Bindings_Map::bind | ( | const char * | id,
|  | const char * | kind,
|  | CORBA::Object_ptr | obj,
|  | CosNaming::BindingType | type
| ) | `[virtual]`

| Add a binding with the specified parameters to the table. Return 0 on success and -1 on failure, 1 if there already is a binding with <id> and <kind>. Implements TAO_Bindings_Map.

size_t TAO_Transient_Bindings_Map::current_size | ( | void |  | ) | `[virtual]`

| Return current number of entries (name bindings) in the underlying hash map. Implements TAO_Bindings_Map.

int TAO_Transient_Bindings_Map::find | ( | const char * | id,
|  | const char * | kind,
|  | CORBA::Object_ptr & | obj,
|  | CosNaming::BindingType & | type
| ) | `[virtual]`

| Find the binding containing <id> and <kind> in the table, and pass binding's type and object back to the caller by reference. Return 0 on success and -1 on failure. Note: a 'duplicated' object reference is assigned to <obj>, so the caller is responsible for its deallocation. Implements TAO_Bindings_Map.

TAO_Transient_Bindings_Map::HASH_MAP & TAO_Transient_Bindings_Map::map | ( | void |  | ) |

| Get a reference to the underlying hash map.

int TAO_Transient_Bindings_Map::rebind | ( | const char * | id,
|  | const char * | kind,
|  | CORBA::Object_ptr | obj,
|  | CosNaming::BindingType | type
| ) | `[virtual]`

| Overwrite a binding containing <id> and <kind> (or create a new one if one doesn't exist) with the specified parameters. Return 0 or 1 on success. Return -1 or -2 on failure. (-2 is returned if the new and old bindings differ in type). Implements TAO_Bindings_Map.

int TAO_Transient_Bindings_Map::shared_bind | ( | const char * | id,
|  | const char * | kind,
|  | CORBA::Object_ptr | obj,
|  | CosNaming::BindingType | type,
|  | int | rebind
| ) | `[private]`

| Helper: factors common code from <bind> and <rebind>.

size_t TAO_Transient_Bindings_Map::total_size | ( | void |  | ) |

| Return the size of the underlying hash table.

int TAO_Transient_Bindings_Map::unbind | ( | const char * | id,
|  | const char * | kind
| ) | `[virtual]`

| Remove a binding containing <id> and <kind> from the table. Return 0 on success and -1 on failure. Implements TAO_Bindings_Map.
