# MessagePack format

MessagePack is an efficient binary serialization format. It lets you exchange data among multiple languages like JSON. But it's faster and smaller. Small integers are encoded into a single byte, and typical short strings require only one extra byte in addition to the strings themselves.

# Dependencies

DataTree API supports 2 MessagePack implementations. For example, to use the official MessagePack API, just add DataTree Adapters and MessagePack JARs to the classpath:

<!-- DATATREE API -->
<dependency>
    <groupId>com.github.berkesa</groupId>
    <artifactId>datatree-adapters</artifactId>
    <version>1.0.15</version>
</dependency>

<!-- MESSAGEPACK API -->
<dependency>
    <groupId>org.msgpack</groupId>
    <artifactId>msgpack</artifactId>
    <version>0.6.12</version>
</dependency>

# Reading and writing using MessagePack adapter

// Parsing MessagePack document
byte[] msgpack = " ... bytes of the MessagePack document ... ";
Tree document = new Tree(msgpack, "msgpack");

// Getting / setting values
InetAddress value = document.get("host").asInetAddress();
document.put("host", InetAddress.getLocalHost());

// Generating MessagePack byte array from Tree
byte[] msgpack = document.toBinary("msgpack");
