Class DdlValidator.RefObjectPositionComparator

java.lang.Object
  net.sf.farrago.ddl.DdlValidator.RefObjectPositionComparator

All Implemented Interfaces:

Comparator<RefObject>

Enclosing class:

DdlValidator

private class DdlValidator.RefObjectPositionComparator
extends Object
implements Comparator<RefObject>

RefObjectPositionComparator compares RefObjects based on their position within the owning DdlValidator's DdlValidator.parserContextMap. Handles the case where position information is not available (all comparisons return equality) and even the unlikely case where only partial position information is available (RefObjects with positions compare before those without).
