Method Details

getMessageProperties

public abstract AQMessageProperties getMessageProperties()
                                                  throws SQLException

Retrieves the properties of the new message.

Throws:

SQLException

getRegistration

public abstract String getRegistration()
                                throws SQLException

Retrieves the registration name which is the name that you provided when you registered for AQ notification with the registerAQNotification method.

In the case of a single consumer queue, the registration name is the name of the queue whereas in the case of a multi-consumer queue, it's the name of the queue plus the name of the consumer ("SCOTT.MY_QUEUE:RECEIVER").

Throws:

SQLException

getPayload

public abstract byte[] getPayload()
                           throws SQLException

Retrieves the payload of the new message. Note that this feature only works with RAW queues and that it needs to be activated with the OracleConnection.NTF_AQ_PAYLOAD option during registration.

Throws:

SQLException

getQueueName

public abstract String getQueueName()
                             throws SQLException

Throws:

SQLException

getConsumerName

public abstract String getConsumerName()
                                throws SQLException

Retrieves the name of the consumer. In the case of a multi-consumer queue, this retrieves the name of the consumer upon which you register for AQ notification.

Throws:

SQLException

getConnectionInformation

public abstract String getConnectionInformation()

Retrieves a description of the TCP connection on which the notification was received.

getEventType

public abstract AQNotificationEvent.EventType getEventType()
