water.util

Class JSONValue<V>

java.lang.Object

water.Iced

water.util.JSONValue<V>

Type Parameters:

V -

All Implemented Interfaces:

java.io.Externalizable, java.io.Serializable, java.lang.Cloneable, Freezable

public class JSONValue<V>
extends Iced

CLass providing encapsulation for json values, especially for parts of json objects with polymorphic values. Idea is to store json (or part of json object) as json string + class for serialization. It can then later be parsed dynamically using the provided `value` and `valueAs` methods.
