Class RelationEvaluatorNode

java.lang.Object

tools.refinery.interpreter.rete.network.BaseNode

tools.refinery.interpreter.rete.network.StandardNode

tools.refinery.interpreter.rete.eval.RelationEvaluatorNode

All Implemented Interfaces:

Clearable, NetworkStructureChangeSensitiveNode, Node, Supplier

public class RelationEvaluatorNode
extends StandardNode
implements Supplier, Clearable

A node that operates in batch-style (see

invalid reference

Receiver#doesProcessUpdatesInBatch()

and evaluates arbitrary Java logic represented by an IRelationEvaluator on the input relations. This is the backing computation node of a RelationEvaluation constraint.

Since:

2.8
