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.

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.
