All Implemented Interfaces:
  NodeHandler

public class ElementHandlerBase
extends ElementHandler

This class is the default element handler from which user-defined element handlers can inherit. It is provided for convenience: use is optional. The individual methods of the default element handler do nothing with the content; in a subclass it is therefore only necessary to implement those methods that need to do something specific.

The startElement() method calls applyTemplates(), so child elements will always be processed.

Constructor Summary
`ElementHandlerBase()`

Method Summary
`boolean` `needsStackFrame()` Optimization hint to allow a handler to declare that it needs no stack space for local variables and parameters
`void` `start(NodeInfo node, Context context)` implement start() method
`void` `startElement(NodeInfo e, Context context)` Define action to be taken before an element of this element type. Default implementation does nothing, other than causing subordinate elements to be processed in the same mode as the caller
