# jackson-dataformat-msgpack

**This project is merged to msgpack-java!!** Yay!

**See [msgpack-java/msgpack-jackson](https://github.com/msgpack/msgpack-java/blob/develop/msgpack-jackson/README.md) for the updated documents**

# Overview

[![Build Status](https://travis-ci.org/komamitsu/jackson-dataformat-msgpack.svg)](https://travis-ci.org/komamitsu/jackson-dataformat-msgpack)

This Jackson extension library handles reading and writing of data encoded in [MessagePack](http://msgpack.org/) data format.
It extends standard Jackson streaming API (`JsonFactory`, `JsonParser`, `JsonGenerator`), and as such works seamlessly with all the higher level data abstractions (data binding, tree model, and pluggable extensions).

## Maven dependency

To use this module on Maven-based projects, use following dependency:

```
<dependency>
  <groupId>org.komamitsu</groupId>
  <artifactId>jackson-dataformat-msgpack</artifactId>
  <version>0.0.3</version>
</dependency>
```

## Usage

Only thing you need to do is to instantiate MessagePackFactory and pass it to the constructor of ObjectMapper.

```
  ObjectMapper objectMapper = new ObjectMapper(new MessagePackFactory());
  ExamplePojo orig = new ExamplePojo("komamitsu");
  byte[] bytes = objectMapper.writeValueAsBytes(orig);
  ExamplePojo value = objectMapper.readValue(bytes, ExamplePojo.class);
  System.out.println(value.getName()); // => komamitsu
```

Also, you can exchange data among multiple languages.

Java

```
  // Serialize
  Map<String, Object> obj = new HashMap<String, Object>();
  obj.put("foo", "hello");
  obj.put("bar", "world");
  byte[] bs = objectMapper.writeValueAsBytes(obj);
  // bs => [-126, -93, 102, 111, 111, -91, 104, 101, 108, 108, 111,
  //        -93, 98, 97, 114, -91, 119, 111, 114, 108, 100]
```

Ruby

```
  require 'msgpack'

# Deserialize
  xs = [-126, -93, 102, 111, 111, -91, 104, 101, 108, 108, 111,
        -93, 98, 97, 114, -91, 119, 111, 114, 108, 100]
  MessagePack.unpack(xs.pack("C*"))
  # => {"foo"=>"hello", "bar"=>"world"}

# Serialize
  ["zero", 1, 2.0, nil].to_msgpack.unpack('C*')
  # => [148, 164, 122, 101, 114, 111, 1, 203, 64, 0, 0, 0, 0, 0, 0, 0, 192]
```

Java

```
  // Deserialize
  bs = new byte[] {(byte) 148, (byte) 164, 122, 101, 114, 111, 1,
                   (byte) 203, 64, 0, 0, 0, 0, 0, 0, 0, (byte) 192};
  TypeReference<List<Object>> typeReference = new TypeReference<List<Object>>(){};
  List<Object> xs = objectMapper.readValue(bs, typeReference);
  // xs => [zero, 1, 2.0, null]
```
