/**
 * A marker interface used to trigger post-deserialization initialization of an object. This works in the same way as
 * {@link Cloneable} interface. Implementors of this interface must add the method
 * <code>private void initAfterDeserialization(MuleContext muleContext) throws MuleException</code> to their class (note that it's
 * private). This will get invoked after the object has been deserialized passing in the current mulecontext when using either
 * {@link org.mule.runtime.core.transformer.wire.SerializationWireFormat},
 * {@link org.mule.runtime.core.transformer.wire.SerializedMuleMessageWireFormat}, or the
 * {@link org.mule.runtime.core.transformer.simple.ByteArrayToSerializable} transformer.
