Method Detail

### scanRootElementHook

    protected boolean scanRootElementHook()
                                   throws java.io.IOException,
                                          org.apache.xerces.xni.XNIException

  Scan for root element hook. This method is a hook for subclasses to add code that handles scanning for the root element. This method will also attempt to remove DTD validator from the pipeline, if there is no DTD grammar. If DTD validator is no longer in the pipeline bind namespaces in the scanner.

  Overrides:
    `scanRootElementHook` in class `XMLDocumentScannerImpl.ContentDispatcher`
  Returns:
    True if the caller should stop and return true which allows the scanner to switch to a new scanning dispatcher. A return value of false indicates that the content dispatcher should continue as normal.
  Throws:
    `java.io.IOException`
    `org.apache.xerces.xni.XNIException`
