EvaluatorRef (ZK Kernel 10.3.0.FL.20260120 API)

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 might be not (depends on the implementation).
- 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.
