Interface EvaluatorRef

All Superinterfaces:

Evaluator, java.io.Serializable

public interface EvaluatorRef
extends Evaluator, java.io.Serializable

A reference to Evaluator. Thought it also implements Evaluator, it is different in two ways:

• It is serializable, while Evaluator is not.
• It is late-binding to the real evaluator. The evaluator is accessed only Evaluator.evaluate(org.zkoss.zk.ui.Page, org.zkoss.xel.Expression), Evaluator.parseExpression(java.lang.String, java.lang.Class), or getEvaluator() is called.
