All Known Implementing Classes:

AmqpJmsStreamMessageFacade

public interface JmsStreamMessageFacade
extends JmsMessageFacade

Interface for a Message Facade that wraps a stream or list based provider message instance. The interface provides the basic entry points into a stream style message where primitive values are read and written as opaque objects.

copy

JmsStreamMessageFacade copy()
                     throws jakarta.jms.JMSException

Description copied from interface: JmsMessageFacade

Create a new instance and perform a deep copy of this object's contents.

Specified by:

a deep copy of this Message Facade including a complete copy of the byte contents of the wrapped message.

Throws:

jakarta.jms.JMSException - if an error occurs while copying the message.

hasNext

boolean hasNext()

true if the stream contains another element beyond the current.

peek

java.lang.Object peek()

Returns:

the next value in the stream without removing it.

Throws:

jakarta.jms.MessageEOFException - if end of message stream has been reached.

pop

void pop()
  throws jakarta.jms.MessageEOFException

Pops the next element in the stream.

Throws:

jakarta.jms.MessageEOFException - if end of message stream has been reached.

put

void put(java.lang.Object value)

Writes a new object value to the stream. If the value provided is a byte[] its entry then it is assumed that it was copied by the caller and its value will not be altered by the provider.
