Class OMXMLStreamReaderValidator

java.lang.Object
  extended by org.apache.axiom.om.util.OMXMLStreamReaderValidator
All Implemented Interfaces:
javax.xml.stream.XMLStreamConstants, javax.xml.stream.XMLStreamReader, OMAttachmentAccessor, OMXMLStreamReader

public class OMXMLStreamReaderValidator
extends Object
implements OMXMLStreamReader

There are several places in the code where events are passed from a source to a consumer using XMLStreamReader events. OMXMLStreamReader (impl)--> consumer of XMLStreamReader events This simple class can be interjected as a filter and used to do some simple validation. Validating the events coming from source (impl) can help find and correct errors when they occur. Otherwise the errors may be caught much further downstream and hard to fix. OMXMLStreamReader (impl)--> OMXMLStreamReaderValiator-> consumer of XMLStreamReader events In the initial version, the XMStreamValidator ensures that the start element events match the end element events.
