Class JsonParserWriter

java.lang.Object
  java.io.Writer
      com.ibm.portal.streaming.json.JsonParserWriter

All Implemented Interfaces:

JsonContentHandlerProvider, JsonStream, java.io.Closeable, java.io.Flushable, java.lang.Appendable, java.nio.channels.Channel

public abstract class JsonParserWriter
extends java.io.Writer
implements JsonContentHandlerProvider, java.nio.channels.Channel, JsonStream

Parser that decomposes a JSON stream into callbacks to JsonContentHandler. The JSON content to be parsed is written onto the parser using the Writer methods. The writer must be closed via Closeable.close() to complete the event sequence. New content can be parsed by reinitializing the parser using the reset() method. The parser will parse a sequence of JSON objects and generates JsonContentHandler.startDocument() and JsonContentHandler.endDocument() callbacks for each detected object in the stream. All content between JSON objects is considered garbage and will not be communicated to the handler.
