Method Detail

getSheetId

public int getSheetId()

Fetch our sheet ID, as found from a PersistPtrHolder. Should match the RefId of our matching SlidePersistAtom

setSheetId

public void setSheetId(int id)

Set our sheet ID, as found from a PersistPtrHolder

getLastOnDiskOffset

public int getLastOnDiskOffset()

Fetch our location on the disk, as of the last write out

setLastOnDiskOffset

public void setLastOnDiskOffset(int offset)

Update the Record's idea of where on disk it lives, after a write out. Use with care...

Specified by:

setLastOnDiskOffset in interface PositionDependentRecord

updateOtherRecordReferences

public void updateOtherRecordReferences(Hashtable<Integer,Integer> oldToNewReferencesLookup)

Since we're a container, we don't mind if other records move about. If we're told they have, just return straight off.
