Member Function Documentation

int TAO_Storable_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>. Reimplemented from TAO_Bindings_Map.

size_t TAO_Storable_Bindings_Map::current_size (  void    )  [virtual]

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

int TAO_Storable_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. Reimplemented from TAO_Bindings_Map.

TAO_Storable_Bindings_Map::HASH_MAP & TAO_Storable_Bindings_Map::map (  void    )

Get a reference to the underlying hash map.

const char * TAO_Storable_Bindings_Map::name (    )  [virtual]

int TAO_Storable_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). Reimplemented from TAO_Bindings_Map.

int TAO_Storable_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_Storable_Bindings_Map::total_size (  void    )

Return the size of the underlying hash table.

int TAO_Storable_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. Reimplemented from TAO_Bindings_Map.

void TAO_Storable_Bindings_Map::Write (  TAO_Writer_Base &    wrtr )  [virtual]

Reimplemented from TAO_Storable_Base.
