Detailed Description

Helper class for use of perfect hashing operation lookup strategy.

This class declares pure virtual methods called 'lookup ()' and 'hash ()' which will be generated by the GPERF program. These methods are used by 'bind ()' and 'find ()' methods. Subclasses will define the lookup and hash functions.

Member Function Documentation

bind()

int TAO_Perfect_Hash_OpTable::bind ( const char * opname, const TAO::Operation_Skeletons skel_ptr )

overridevirtual

Associate the skeleton skel_ptr with an operation named opname. Returns -1 on failure, 0 on success, 1 on duplicate.

Implements TAO_Operation_Table.

find() [1/2]

int TAO_Perfect_Hash_OpTable::find ( const char * opname, TAO_Collocated_Skeleton & skelfunc, TAO::Collocation_Strategy s, const unsigned int length = 0 )

overridevirtual

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.

find() [2/2]

int TAO_Perfect_Hash_OpTable::find ( const char * opname, TAO_Skeleton & skelfunc, const unsigned int length = 0 )

overridevirtual

See the documentation in the base class for details.

Implements TAO_Operation_Table.

hash()

virtual unsigned int TAO_Perfect_Hash_OpTable::hash ( const char * str, unsigned int len )

lookup()

virtual const TAO_operation_db_entry * TAO_Perfect_Hash_OpTable::lookup ( const char * str, unsigned int len )
