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 Function Documentation

bind()

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.

current_size()

size_t TAO_Transient_Bindings_Map::current_size ( )

virtual

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

Implements TAO_Bindings_Map.

find()

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.

map()

TAO_Transient_Bindings_Map::HASH_MAP & TAO_Transient_Bindings_Map::map

(

)

Get a reference to the underlying hash map.

rebind()

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.

shared_bind()

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>.

total_size()

size_t TAO_Transient_Bindings_Map::total_size

(

)

Return the size of the underlying hash table.

unbind()

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.
