Class Mapping

java.lang.Object

graphql.schema.diffing.Mapping

public class Mapping
extends java.lang.Object

A mapping (in the math sense) from a list of vertices to another list of vertices. A mapping can semantically mean a change, but doesn't have to: a vertex can be mapped to the same vertex (semantically the same, Java object wise they are different).
