Method Detail

setDisableMessageID

public void setDisableMessageID(boolean value)
                         throws JMSException
Sets whether message IDs can be disabled.

Since message ID's take some effort to create and increase a message's size, some JMS providers may be able to reduce message overhead if they are given a hint that message IDs are not used by an application. When a client sets a Producer to disable message IDs, it is saying that no one depends on the message IDs of the messages it produces. Produced messages must then either have message ID set to null or, if the hint is ignored, have message ID set to its normal unique value.

Message IDs are enabled by default.

Specified by:
setDisableMessageID in interface MessageProducer
Parameters:
value - hint that message IDs can be disabled
Throws:
JMSException - if the disable message IDs hint is not set due to some error.

getDisableMessageID

public boolean getDisableMessageID()
                            throws JMSException
Gets an indication of whether message IDs are disabled.

Note that the returned value reflects the client-provided hint and can therefore only be used to determine whether or not message IDs might be set to null, not if they are being set to null.

Specified by:
getDisableMessageID in interface MessageProducer
Returns:
an indication of whether message IDs are disabled
Throws:
JMSException - if the disable message IDs hint is not retrieved due to some error.

setDisableMessageTimestamp

public void setDisableMessageTimestamp(boolean value)
                                throws JMSException
Sets whether message timestamps can be disabled.

Message timestamps are enabled by default.

Specified by:
setDisableMessageTimestamp in interface MessageProducer
Parameters:
value - hint that message timestamps can be disabled
Throws:
JMSException - if the disable message timestamp hint is not set due to some error.

getDisableMessageTimestamp

public boolean getDisableMessageTimestamp()
                                   throws JMSException
Gets an indication of whether message timestamps are disabled.

Note that the returned value reflects the client-provided hint and can therefore only be used to determine whether or not message timestamps might be set to zero, not if they are being set to zero.

Specified by:
getDisableMessageTimestamp in interface MessageProducer
Returns:
an indication of whether message IDs are disabled
Throws:
JMSException - if the disable message timestamp hint is not retrieved due to some error.

setDeliveryMode

public void setDeliveryMode(int deliveryMode)
                     throws JMSException
Sets this producer's default delivery mode.

Delivery mode is set to PERSISTENT by default.

Specified by:
setDeliveryMode in interface MessageProducer
Parameters:
deliveryMode - the message delivery mode for this message producer (PERSISTENT or NON_PERSISTENT)
Throws:
JMSException - if the delivery mode is not set due to some error.
See Also:
MessageProducer.getDeliveryMode(), DeliveryMode.NON_PERSISTENT, DeliveryMode.PERSISTENT, Message.DEFAULT_DELIVERY_MODE

getDeliveryMode

public int getDeliveryMode()
                    throws JMSException
Gets this producer's default delivery mode.
Specified by:
getDeliveryMode in interface MessageProducer
Returns:
the message delivery mode
Throws:
JMSException - if the delivery mode is not retrieved due to some error.
See Also:
MessageProducer.setDeliveryMode(int)

setPriority

public void setPriority(int priority)
                 throws JMSException
Sets this producer's default priority. JMS defines a ten level priority value with 0 as the lowest priority and 9 as the highest. Priority is set to 4 by default.
Specified by:
setPriority in interface MessageProducer
Parameters:
priority - the message priority for this message producer
Throws:
JMSException - if the priority is not set due to some error.
See Also:
MessageProducer.getPriority(), Message.DEFAULT_PRIORITY

getPriority

public int getPriority()
                throws JMSException
Gets this producer's default priority. JMS defines a ten level priority value with 0 as the lowest priority and 9 as the highest.
Specified by:
getPriority in interface MessageProducer
Returns:
the message priority
Throws:
JMSException - if the priority is not retrieved due to some error.
See Also:

setTimeToLive

public void setTimeToLive(long timeToLive)
                   throws JMSException
Sets the default length of time in milliseconds from its dispatch time that a produced message should be retained by the message system.

Time-to-live is set to zero by default.

Specified by:
setTimeToLive in interface MessageProducer
Parameters:
timeToLive - the message time-to-live in milliseconds; zero is unlimited
Throws:
JMSException - if time-to-live is not set due to some error.

close

public void close()

Description copied from interface: MessageProducer
Closes the message producer.

Since a provider may allocate some resources on behalf of a MessageProducer outside the Java virtual machine, clients should close them when they are not needed. Relying on garbage collection to eventually reclaim these resources may not be timely enough.

Specified by:
close in interface MessageProducer
Overrides:
close in class oracle.jms.AQjmsObject
Throws:
JMSException - if the JMS provider fails to close the producer due to some internal error.

getDestination

public Destination getDestination()
                           throws JMSException
Gets the destination associated with this MessageProducer.
Specified by:
getDestination in interface MessageProducer
Returns:
this producer's Destination/
Throws:
JMSException - if the destination is not retrieved due to some error.
Since:
1.1

send

public void send(Destination destination,
                 Message message)
          throws JMSException
Sends a message to a destination for an unidentified message producer. Uses this MessageProducer's default delivery mode, priority, and time to live.

Typically, a message producer is assigned a destination at creation time; however, the JMS API also supports unidentified message producers, which require that the destination be supplied every time a message is sent.

Specified by:
send in interface MessageProducer
Parameters:
destination - the destination to send this message to
message - the message to send
Throws:
JMSException - if the message is not sent due to some error.
MessageFormatException - if an invalid message is specified.
InvalidDestinationException - if a client uses this method with an invalid destination.
java.lang.UnsupportedOperationException - if a client uses this method with a MessageProducer that specified a destination at creation time.
Since:
1.1
See Also:
Session.createProducer(javax.jms.Destination), MessageProducer

send

public void send(Destination destination,
                 Message message,
                 int deliveryMode,
                 int priority,
                 long timeToLive)
          throws JMSException
Sends a message to a destination for an unidentified message producer, specifying delivery mode, priority and time-to-live.

Typically, a message producer is assigned a destination at creation time; however, the JMS API also supports unidentified message producers, which require that the destination be supplied every time a message is sent.

Specified by:
send in interface MessageProducer
Parameters:
destination - the destination to send this message to
message - the message to send
deliveryMode - the delivery mode for message (DeliveryMode.PERSISTENT or DeliveryMode.NON_PERSISTENT)

timeToLive - the time-to-live for message (milliseconds; 0 means no limit)
Throws:
JMSException - if the message is not sent due to some error.
MessageFormatException - if an invalid message is specified.
InvalidDestinationException - if a client uses this method with an invalid destination.
Since:
1.1
See Also:
Session.createProducer(javax.jms.Destination)

bufferSend

public void bufferSend(Destination destination,
                       Message message,
                       int priority,
                       long timeToLive)
                throws JMSException
Sends a non-persistent message to an in-memory portion of the destination for an unidentified message producer, specifying priority and time-to-live.
