Class FIleBasedDAO

java.lang.Object
  org.lsst.ccs.config.FIleBasedDAO

Direct Known Subclasses:

MemoryDAO

public class FIleBasedDAO
extends Object

Creates a dummy file-based Configuration database. all history operations are unsupported (as are SQL requests). The numbering scheme for ID are negative values and so can be detected
