Interface PositionDependentRecord

All Known Implementing Classes:

BinaryTagDataBlob, Document, DummyPositionSensitiveRecordWithChildren, Environment, ExOleObjStg, MainMaster, Notes, PersistPtrHolder, PositionDependentRecordAtom, PositionDependentRecordContainer, SheetContainer, Slide, UserEditAtom

public interface PositionDependentRecord

Records which either care about where they are on disk, or have other records who care about where they are, will implement this interface. Normally, they'll subclass PositionDependentRecordAtom or PositionDependentRecordContainer, which will do the work of providing the setting and updating interfaces for them. This is a special (and dangerous) kind of Record. When created, they need to be pinged with their current location. When written out, they need to be given their new location, and offered the list of records which have changed their location.
