Public Methods

public boolean dispatch (boolean complete)

Dispatch an XML "event".

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
IOException Thrown on i/o error.
XNIException Thrown on parse error.

Protected Methods

protected boolean elementDepthIsZeroHook ()

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.

protected void endOfFileHook (EOFException e)

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.

protected boolean scanForDoctypeHook ()

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.

protected boolean scanRootElementHook ()

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.
