Examples of de.danet.an.workflow.util.SAXEventBufferImpl

de.danet.an.workflow.util.SAXEventBufferImpl
This class implements the interface SAXEventBuffer using the SAXContentBuffer as base class. SAXContentBuffer cannot implement SAXEventBuffer directly, as SAXEventBuffer is an interface from the workflow API and SAXContentBuffer is part of the general purpose utility library. @author @version $Revision: 1607 $
