All Implemented Interfaces:

public class ExceptionInsertingFilter
extends FullXmlFilter

XMLFilter to reinsert exceptions into a XMLFilter chain. Typical use case is in a XMLFilter chain with a streaming XSLT. In that case, the actual processing of the XSLT in the tail of the chain is performed internally in a different thread than the provisioning of events from the head of the chain. Exceptions in the tail of the chain do not reach the head then. In such a situation the ExceptionInsertingFilter can be used in the head of the chain, to receive unhandled exceptions of the tail.
