Class ELResolverBase

java.lang.Object

javax.el.ELResolver

com.liferay.faces.util.el.ELResolverBase

All Implemented Interfaces:

Serializable

public abstract class ELResolverBase
extends javax.el.ELResolver
implements Serializable

This is a convenience base class that extends ELResolver. A subclasses must be designed to be instantiated as a singleton because the JavaDoc for Application.getELResolver() indicates that an ELResolver should be a singleton instance. This class implements the Serializable interface as a clue to subclasses that they should implement a stateless, thread-safe singleton design. Subclasses should call the static addFeatureDescriptor(String, Class) method from a static block in order to add to the list of feature descriptors.
