## Detailed Description

Dynamic Hashing scheme for CORBA IDL operation name lookup.

## Member Typedef Documentation

typedef ACE_Hash_Map_Manager_Ex<const char *, TAO::Operation_Skeletons, ACE_Hash<const char *>, ACE_Equal_To<const char *>, ACE_Null_Mutex> TAO_Dynamic_Hash_OpTable::OP_MAP_MANAGER`[private]`

## Constructor & Destructor Documentation

TAO_BEGIN_VERSIONED_NAMESPACE_DECL TAO_Dynamic_Hash_OpTable::TAO_Dynamic_Hash_OpTable | ( | const TAO_operation_db_entry * | db,
|  | CORBA::ULong | dbsize,
|  | CORBA::ULong | hashtblsize,
|  | ACE_Allocator * | alloc |
| ) |  |  |

Initialize the dynamic hash operation table with a database of operation names. The hash table size may be different from the size of the database. Hence we use the third argument to specify the size of the internal hash table. The <alloc> argument is used to determine where the memory comes from (usually from <ACE_Static_Allocator_Base>).

TAO_Dynamic_Hash_OpTable::~TAO_Dynamic_Hash_OpTable | ( | void |  | ) |

Destructor.

## Member Function Documentation

int TAO_Dynamic_Hash_OpTable::bind | ( | const char * | opname,
|  | const TAO::Operation_Skeletons | skel_ptr |
| ) |  |  | `[virtual]`

See the documentation in the base class for details.

Implements TAO_Operation_Table.

int TAO_Dynamic_Hash_OpTable::find | ( | const char * | opname,
|  | TAO_Collocated_Skeleton & | skelfunc,
|  | TAO::Collocation_Strategy | s,
|  | const unsigned int | length = `0` |
| ) |  |  | `[virtual]`

Uses opname to look up the collocated skeleton function and pass it back in skelfunc. Returns non-negative integer on success, or -1 on failure.

Implements TAO_Operation_Table.

int TAO_Dynamic_Hash_OpTable::find | ( | const char * | opname,
|  | TAO_Skeleton & | skelfunc,
|  | const unsigned int | length = `0` |
| ) |  |  | `[virtual]`

Uses opname to look up the skeleton function and pass it back in skelfunc. Returns non-negative integer on success, or -1 on failure.

Implements TAO_Operation_Table.
