Method Summary

Modifier and Type	Method and Description
void	copyInto(AmqpObjectTypeDelegate copy) Copy the internal data into the given instance.
Serializable	getObject() Read a Serialized object from the AMQP message using the strategy implemented by this delegate.
boolean	hasBody()
boolean	isAmqpTypeEncoded()
void	onSend() Signals that the message is about to be sent so we should ensure proper state of the marshaled object and message annotations prior to that.
void	setObject(Serializable value) Given a serializable instance, store the value into the AMQP message using the strategy implemented by this delegate.

Method Detail

setObject

void setObject(Serializable value)
        throws IOException

Given a serializable instance, store the value into the AMQP message using the strategy implemented by this delegate.
