A marker interface that is used to indicate that an IMessage has an alternative smaller form for serialization.

Methods

getSmallMessage():IMessage

This method must be implemented by subclasses that have a "small" form, typically achieved through the use of flash.utils.IExternalizable. If a small form is not available this method should return null.

Returns:

Returns An alternative representation of an flex.messaging.messages.IMessage so that the serialized form is smaller than the regular message.
