MessagePack Java 0.6.X 动态类型

我们知道 Java 是一个静态类型的语言。通过输入 Value MessagePack能够实现动态的特性。

Value 有方法来检查自己的类型（isIntegerType(), isArrayType(), 等...)，同时也转换为自己的类型 (asStringValue(), convert(Template)）。

本代码可以在 https://github.com/cwiki-us-demo/messagepack-6-demo-java/blob/master/src/test/java/com/insight/demo/msgpack/MessagePack6DynamicTyping.java 中查看。
