Method Detail

elementDepthIsZeroHook

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.

endOfFileHook

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.

resolveExternalSubsetAndRead

protected void resolveExternalSubsetAndRead()

Attempt to locate an external subset for a document that does not otherwise have one. If an external subset is located, then it is scanned.

scanForDoctypeHook

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.

scanRootElementHook

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.
