Interface LayerData

All Superinterfaces:

java.lang.Comparable

All Known Implementing Classes:

ArchiveLayerData, BlankLayerData, DirtyLayerData, RawLayerData

public interface LayerData
extends java.lang.Comparable

For each layer that the DBData is been viewed through a Layer Data object is created. Each Layer Data record holds a list of the Layer Field objects which are non blank in this layer ( or are blanking out the layer below) THREAD MODE: MULTI-THREADED shared but non-mutable
