Detailed Description

This interface is implemented by an application to handle the parsing events that are generated by the JSON parser.

This is a callback object that is registered using the P6R::p6IJSONReader::setContentHandler() method and is the main parsing interface to the application. It provides a stream of events for each item in the input JSON document. Each event results in a method call to one of the methods below.

* Given the simple JSON document:
* { "menuitem": "File",
* "offsets": [ 44, 99 ]
* }
*
* The following sequence of callbacks would happen in the application written instance of
* the P6IJSONContentHandler interface:
*
* startDocument()
* startObject( 1 ) - {
* startPair() - menuitem
* value() - File (P6JSON_TYPE_STR)
* startPair() - offsets (P6JSON_TYPE_STR)
* startArray( 1 ) - [
* value() - 44 (P6JSON_TYPE_INTEGER)
* value() - 99 (P6JSON_TYPE_INTEGER)
* endArray( 1 ) - ]
* endObject( 1 ) - }
* endDocument()
*
