Represents a parser configuration that can be used as the
configuration for a "pull" parser. A pull parser allows the
application to drive the parser instead of having document
information events "pushed" to the registered handlers.

A pull parser using this type of configuration first calls
the setInputSource method. After the input
source is set, the pull parser repeatedly calls the
parse(boolean):boolean method. This method
returns a value of true if there is more to parse in the
document.

Calling the parse(XMLInputSource) is equivalent
to setting the input source and calling the
parse(boolean):boolean method with a "complete"
value of true.

Sets the input source for the document to parse.
Params:
inputSource – The document's input source.
Throws:
XMLConfigurationException – Thrown if there is a
                       configuration error when initializing the
                       parser.
IOException – Thrown on I/O error.

Parses the document in a pull parsing fashion.
Params:
complete – True if the pull parser should parse the
                remaining document completely.
Throws:
XNIException – Any XNI exception, possibly wrapping
                        another exception.
IOException –  An IO exception from the parser, possibly
                        from a byte stream or character stream
                        supplied by the parser.

If the application decides to terminate parsing before the xml document
