Constructor Detail

AmqpSerializedObjectDelegate

public AmqpSerializedObjectDelegate(AmqpJmsMessageFacade parent,
                                    JmsDeserializationPolicy deserializationPolicy)

Create a new delegate that uses Java serialization to store the message content.

Parameters:

parent - the AMQP message facade instance where the object is to be stored / read.

deserializationPolicy - the JmsDeserializationPolicy that is used to validate the security of message content, may be null (e.g on new outgoing messages).

Method Detail

getObject

public Serializable getObject()
                       throws IOException,
                              ClassNotFoundException

Description copied from interface: AmqpObjectTypeDelegate

Read a Serialized object from the AMQP message using the strategy implemented by this delegate.

Specified by:

getObject in interface AmqpObjectTypeDelegate

Returns:

an Object that has been read from the stored object data in the message.

Throws:

IOException - if an error occurs while reading the stored object.

ClassNotFoundException - if no class can be found for the stored type.

setObject

public void setObject(Serializable value)
               throws IOException

Description copied from interface: AmqpObjectTypeDelegate

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

Specified by:

setObject in interface AmqpObjectTypeDelegate

Parameters:

value - A serializable object instance to be stored in the message.

Throws:

IOException - if an error occurs during the store operation.

onSend

public void onSend()

Description copied from interface: AmqpObjectTypeDelegate

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.

Specified by:

onSend in interface AmqpObjectTypeDelegate

copyInto

public void copyInto(AmqpObjectTypeDelegate copy)
              throws Exception

Description copied from interface: AmqpObjectTypeDelegate

Copy the internal data into the given instance.

Specified by:

copyInto in interface AmqpObjectTypeDelegate

Parameters:

copy - the new delegate that will receive a copy of this instances object data.

Throws:

Exception - if an error occurs while copying the contents to the target.

isAmqpTypeEncoded

public boolean isAmqpTypeEncoded()

Specified by:

isAmqpTypeEncoded in interface AmqpObjectTypeDelegate

isTrusted

public boolean isTrusted(Class<?> clazz)

Specified by:

isTrusted in interface ClassLoadingAwareObjectInputStream.TrustedClassFilter

hasBody

public boolean hasBody()

Specified by:

hasBody in interface AmqpObjectTypeDelegate
