Class DiffEqualityMapping

java.lang.Object

com.netflix.hollow.tools.diff.exact.DiffEqualityMapping

public class DiffEqualityMapping
extends java.lang.Object

The HollowDiff uses this class to expedite diff processing -- this class determines pairs of records which are exactly equal. This calculation is relatively easy, and these record pairs can be entirely excluded while diffing a hierarchy. Not intended for external consumption.
