Class BeanCoder

java.lang.Object

com.ebay.jsoncoder.BeanCoder

public class BeanCoder
extends Object

A coder to convert java class to a TDNode

For an array or collection object, it will be encoded as TDNode of type ARRAY

For Java Beans, it will be converted into TDNode of type MAP

For some simple types such as Date, int, it will be converted TDNode of type SIMPLE

As this encoder won't store any type information, it will only infer the type from the class. For collections fields, the element type information has to be specified with generic type. If not specified, the $type attribute need to be provided. Otherwise
