Interface Evaluation

All Superinterfaces:

java.io.Serializable

public interface Evaluation
extends java.io.Serializable

for implementation of callback evaluations.

To constrain a Query node with your own callback Evaluation, construct an object that implements the Evaluation interface and register it by passing it to Query#constrain(Object).

Evaluations are called as the last step during query execution, after all other constraints have been applied. Evaluations in higher level Query nodes in the query graph are called first.

Method Summary

void	evaluate(Candidate candidate) callback method during query execution.
int	getActivationDepth() get activation depth for evaluation object.

Parameters:
