Rose::Combinatorics::Hasher::HasherFactory Class Reference

Description

HasherFactory is a singleton that creates and returns Hashers by name.

Hasher factory contains a map of names to HasherMaker . When createHasher is passed a name, it will attempt to create the correct Hasher and pass it back. Users can add Hashers to HasherFactory using . HasherFactory is created when Instance is first called. Generally this is done at module initialization time.
