Class CasSeqAddrMaps


  • public class CasSeqAddrMaps
    extends java.lang.Object
    Manage the conversion of Items (FSrefs) to relative sequential index number, and back Manage the difference in two type systems both size of the FSs and handling excluded types During serialization, these maps are constructed before serialization. During deserialization, these maps are constructed while things are being deserialized, and then used in a "fixup" call at the end. This allows for forward references. For delta deserialization, the base part of these maps (for below-the-line) is constructed by scanning up to the mark.
