Class JSONParser

java.lang.Object

com.sdicons.json.parser.JSONParser

public class JSONParser
extends Object

Reads JSON text and convert it into a Java model for further handling.

 
 // Open a JSON file in the classpath.
 final JSONParser lParser = new JSONParser(JSONTest.class.getResourceAsStream("/example.json"));
 // Parse the first object in the file.
 final JSONValue lMyObject = lParser.nextValue();
 
 

After the parsing you have an object from the JSON model from package com.sdicons.json.model. You can map it to Java using the JSONMapper or unmarshal it to Java using the JSONSerializer. Note that the rendering to text can be done using the render() method.

JSONParser

public JSONParser(InputStream aStream,
          String aStreamName)
           throws ParserException

Construct a parser using a stream.

Parameters:

aStream - A stream containing JSON text.

aStreamName - A String that describes the stream, it will be attached to all JSON objects in the model which are generated from this parser. This makes it possible to identify the stream where the object came from.

Throws:

ParserException - When an error occurs during parser construction.

Construct a parser using a reader.

Parameters:

aReader - A reader containing JSON text.

aStreamName - A String that describes the stream, it will be attached to all JSON objects in the model which are generated from this parser. This makes it possible to identify the stream where the object came from.

Throws:

ParserException - When an error occurs during parser construction.

public JSONParser(Reader aReader)
           throws ParserException

Construct a parser using a reader.

Parameters:

aReader - A reader containing JSON text.

nextValue

public JSONValue nextValue()
                    throws ParserException

Read the next JSON structure from the stream and convert it into a Java model.

Returns:

A Java object representing the object in the stream.

Throws:

ParserException - When a lexer/parser error occured while parsing the stream.
