MessagePack Java 0.6.X 動態類型

我們知道 Java 是一個靜態類型的語言。通過輸入?Value?MessagePack能夠實現動態的特性。

Value?有方法來檢查自己的類型（isIntegerType(),?isArrayType(), 等...)，同時也轉換為自己的類型 (asStringValue(),?convert(Template)）。

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