Enum DiffStatus

java.lang.Object

java.lang.Enum<DiffStatus>

org.openl.rules.diff.tree.DiffStatus

All Implemented Interfaces:

Serializable, Comparable<DiffStatus>

public enum DiffStatus
extends Enum<DiffStatus>

Result of comparing 2 elements.

As a rule the 2nd element is treated as it is some version of 1st one. But that is not always true.
