All Implemented Interfaces:

EvaluationContext

public class ExternalEdgeRecognizerContext
extends Object
implements EvaluationContext

Context which supports the evaluation and "recognition" of a given external reference or row-key by a binary expression tree.

A sequence uniquely identifies an data graph entity within a local or distributed data graph and is mapped internally to provide global uniqueness.
