Class ImplicitResultChecker

java.lang.Object

net.sf.saxon.event.SequenceReceiver

net.sf.saxon.event.ProxyReceiver

net.sf.saxon.serialize.ImplicitResultChecker

All Implemented Interfaces:

Result, Receiver

public class ImplicitResultChecker
extends ProxyReceiver

This filter is inserted into the serializer pipeline when serializing an implicit XSLT result tree, that is, one that is created without use of xsl:result-document. Its main purpose is to check, if and only if the result destination is actually written to, that it does not conflict with an explicit result destination with the same URI. It also ensures that the output destination is opened before it is first written to.
