All Implemented Interfaces:

Result, Receiver

public class ShallowCopyEventFeed
extends ItemFeed

This event feed implements an implicit xsl:copy instruction used in a built-in template. The events representing the start and end of the input element or document are written to the destination receiver during the open() and close() calls. Between these two calls, the child instruction representing the content of the document or element pushes its output to the same destination receiver.

The instruction-dependent code is contained in the processLeft() and processRight() methods
