65  * Represents a parser configuration that can be used as the
66  * configuration for a "pull" parser. A pull parser allows the
67  * application to drive the parser instead of having document
68  * information events "pushed" to the registered handlers.
69  * <p>
70  * A pull parser using this type of configuration first calls
71  * the <code>setInputSource</code> method. After the input
72  * source is set, the pull parser repeatedly calls the
73  * <code>parse(boolean):boolean</code> method. This method
74  * returns a value of true if there is more to parse in the
75  * document.
76  * <p>
77  * Calling the <code>parse(XMLInputSource)</code> is equivalent
78  * to setting the input source and calling the
79  * <code>parse(boolean):boolean</code> method with a "complete"
80  * value of <code>true</code>.
