  +--net.sf.swan.xml.input.components.Chain

All Implemented Interfaces:

ContextListener

public class Chain

extends java.lang.Object

implements ContextListener

Utility to chain together two ContextListeners. The provided outer component gets start element events before the inner component and end element events after it. Both are passed the event regardless of whether either consumes it. If the single argument constructor is used by a subclass, then this instance itself is the outer component. Text events and processing instructions are by default only passed to the outer component.
