PINDEX PURL::HashFunction (  )  const [virtual]

This function yields a hash value required by the PDictionary# class. A descendent class that is required to be the key of a dictionary should override this function. The precise values returned is dependent on the semantics of the class. For example, the PString# class overrides it to provide a hash function for distinguishing text strings.

The default behaviour is to return the value zero.

hash function value for class instance.
