List of all members.

Public Methods
virtual unsigned int	getHashVal (const void *const key, unsigned int mod)=0
virtual bool	equals (const void *const key1, const void *const key2)=0

Detailed Description

The HashBase interface is the general outline of a hasher. Hashers are used in RefHashTableOf hashtables to hash any type of key. An examples is the HashXMLCh class which is designed to produce hash values for XMLCh* strings. Any hasher inheriting from HashBase may be specified when the RefHashTableOf hashtable is constructed.

Member Function Documentation

virtual bool HashBase::equals (  const void *const    key1, const void *const    key2 )  [pure virtual]

Compares two keys and determines if they are semantically equal Parameters: key1  the first key to be compared key2  the second key to be compared Returns: true if they are equal Implemented in HashCMStateSet, HashPtr, and HashXMLCh.

virtual unsigned int HashBase::getHashVal (  const void *const    key, unsigned int    mod )  [pure virtual]

Returns a hash value based on the key Parameters: key  the key to be hashed mod  the modulus the hasher should use Implemented in HashCMStateSet, HashPtr, and HashXMLCh.
