Class JsonObject<K,V>

java.lang.Object

java.util.AbstractMap<K,V>

java.util.HashMap<K,V>

java.util.LinkedHashMap<K,V>

com.cedarsoftware.util.io.JsonObject<K,V>

Type Parameters:

K - field name in Map-of-Map

V - Value

All Implemented Interfaces:

Serializable, Cloneable, Map<K,V>

public class JsonObject<K,V>
extends LinkedHashMap<K,V>

This class holds a JSON object in a LinkedHashMap. LinkedHashMap used to keep fields in same order as they are when reflecting them in Java. Instances of this class hold a Map-of-Map representation of a Java object, read from the JSON input stream.
