Modifier and Type	Method	Description
void	close()	Closes the reader and releases any in use resources.
org.apache.qpid.proton.amqp.messaging.DeliveryAnnotations	getDeliveryAnnotations()	Once a message has been read but before the reader is closed this API offers access to any delivery annotations that were present upon decode of the read message.
AMQPTunneledCoreLargeMessageReader	open()	Reset any internal state of this reader and prepares it to begin processing a new delivery.
Message	readBytes(org.apache.qpid.proton.engine.Delivery delivery)	Reads the bytes from an incoming delivery which might not be complete yet but allows the reader to consume pending bytes to prevent stalling the sender because the session window was exhausted.

Method Detail

getDeliveryAnnotations

public org.apache.qpid.proton.amqp.messaging.DeliveryAnnotations getDeliveryAnnotations()

Description copied from interface: MessageReader

Once a message has been read but before the reader is closed this API offers access to any delivery annotations that were present upon decode of the read message.

Specified by:

getDeliveryAnnotations in interface MessageReader

Returns:

any DeliveryAnnotations that were read as part of decoding the message.

close

public void close()

Description copied from interface: MessageReader

Closes the reader and releases any in use resources. If the reader was not finished processing an incoming message when closed the reader should release any resources that might be held such as large message files etc.

Specified by:

close in interface MessageReader

open

public AMQPTunneledCoreLargeMessageReader open()

Description copied from interface: MessageReader

Reset any internal state of this reader and prepares it to begin processing a new delivery. A previously closed reader can be reset for reuse.

Specified by:

open in interface MessageReader

Returns:

this MessageReader instance.

readBytes

public Message readBytes(org.apache.qpid.proton.engine.Delivery delivery)
                  throws Exception

Description copied from interface: MessageReader

Reads the bytes from an incoming delivery which might not be complete yet but allows the reader to consume pending bytes to prevent stalling the sender because the session window was exhausted. Once a delivery has been fully read and is no longer partial the readBytes method will return the decoded message for dispatch. Notice that asynchronous Readers will never return the Message but will rather call a complete operation on the Server Receiver.

Specified by:

readBytes in interface MessageReader

Parameters:

delivery - The delivery that has pending incoming bytes.

Throws:

Exception
