Class ExternalizableClassMapping

      org.spicefactory.cinnamon.io.mapping.ExternalizableClassMapping

All Implemented Interfaces:

ClassMapping

public class ExternalizableClassMapping
extends AbstractClassMapping

ClassMapping implementation responsible for mapping ActionScript classes that implement flash.utils.IExternalizable. Additionally these classes must have an alias registered in ActionScript with flash.net.registerClassAlias or the [RemoteClass] metadata tag (which only works in Flex applications).

This implementation basically just delegates the task of encoding/decoding the object to/from AMF3 binary data to the classes that implement Externalizable or Externalizer

Method Detail

init

public void init(CinnamonConfig config)

Description copied from interface: ClassMapping

Parameters:

config - the Cinnamon configuration instance

newJavaInstance

public Object newJavaInstance()

Description copied from interface: ClassMapping

Creates a new instance of the mapped Java class.

Returns:

a new instance of the mapped Java class

readObject

public void readObject(Object instance,
