Class JSONWriter

java.lang.Object
  org.springframework.extensions.webscripts.json.JSONWriter

public final class JSONWriter
extends Object

Fast and simple JSON stream writer. Wraps a Writer to output a JSON object stream. No intermediate objects are created - writes are immediate to the underlying stream. Quoted and correct JSON encoding is performed on string values, - encoding is not performed on key names - it is assumed they are simple strings. The developer must call JSONWriter.encodeJSONString() on the key name if required.
