### XMLDocumentFragmentScannerImpl.FragmentContentDispatcher

    protected XMLDocumentFragmentScannerImpl.FragmentContentDispatcher()

Method Detail

### dispatch

    public boolean dispatch(boolean complete)
                     throws java.io.IOException,
                            org.apache.xerces.xni.XNIException

  Dispatch an XML "event".
  Specified by:
    `dispatch` in interface `XMLDocumentFragmentScannerImpl.Dispatcher`
  Parameters:
    `complete` - True if this dispatcher is intended to scan and dispatch as much as possible.
  Returns:
    True if there is more to dispatch either from this or a another dispatcher.
  Throws:
    `java.io.IOException` - Thrown on i/o error.
    `org.apache.xerces.xni.XNIException` - Thrown on parse error.

### scanForDoctypeHook

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

  Scan for DOCTYPE hook. This method is a hook for subclasses to add code to handle scanning for a the "DOCTYPE" string after the string "
  Returns:
    True if the "DOCTYPE" was scanned; false if "DOCTYPE" was not scanned.

### elementDepthIsZeroHook

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

  Element depth iz zero. This methos is a hook for subclasses to add code to handle when the element depth hits zero. When scanning a document fragment, an element depth of zero is normal. However, when scanning a full XML document, the scanner must handle the trailing miscellanous section of the document after the end of the document's root element.
  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.

### 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. When scanning a document fragment, there is no "root" element. However, when scanning a full XML document, the scanner must handle the root element specially.
  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.

### endOfFileHook

    protected void endOfFileHook(java.io.EOFException e)
                          throws java.io.IOException,
                                 org.apache.xerces.xni.XNIException

  End of file hook. This method is a hook for subclasses to add code that handles the end of file. The end of file in a document fragment is OK if the markup depth is zero. However, when scanning a full XML document, an end of file is always premature.
