Iterator::File::State::Interface -- Interface for Iterator::File state classesDESCRIPTION
All data sources should subclass Iterator::File::State::Interface, overriding methods as appropriate.Iterator::File::State::Interface inherits from Iterator::File::Utility.
- new(%config)
- Each subclass can take a %config hash. Keys/meaning will be specific to each subclass.
- initialize()
- Initilizes any requirements for class. (E.g., prepping temp files.) The iterator is not available until after initialize is invoked.
- advance_marker()
- Increments the marker by one.
- marker()
- Return the current value of the marker.
- set_marker( $num )
- Sets the value of the marker to $num. Note this update is independent of any changes to the source file.
- finish()
- Perform any required clean up once we're done.
