TM::Materialized::File - Topic Maps, abstract class for stream (map) based input/output drivers
# this class will never be directly used for instantiation# see the description in TM and individual low-level drivers
This class is a subclass of TM::Resource, so it implements maps which are connected to a resource. It is abstract, though, as it only defined how a stream-based driver package should behave. It may thus be inherited by classes which implement external formats (TM::Materialized::AsTMa, ....).
Methods The methods of synchronisation is defined here. They should not be directly called by a user, as they will be triggered by "sync_in" and "sync_out" from the superclass. What deriving implementations MUST implement are methods how to deserialize streams into maps and how to serialize maps to streams. If the serialization format supports this, of course. Note: No map consolidation is triggered here. The application has to do this separately. TM Copyright 200[2-6], Robert Barta <[email protected]>, All rights reserved.
