/**
The RQueuedMessage class represents a message in a message queue
or job log.
The following attribute IDs are supported:
- {@link #ALERT_OPTION ALERT_OPTION}
- {@link #DATE_SENT DATE_SENT}
- {@link #DEFAULT_REPLY DEFAULT_REPLY}
- {@link #MESSAGE_FILE MESSAGE_FILE}
- {@link #MESSAGE_HELP MESSAGE_HELP}
- {@link #MESSAGE_ID MESSAGE_ID}
- {@link #MESSAGE_KEY MESSAGE_KEY}
- {@link #MESSAGE_QUEUE MESSAGE_QUEUE}
- {@link #MESSAGE_SEVERITY MESSAGE_SEVERITY}
- {@link #MESSAGE_TEXT MESSAGE_TEXT}
- {@link #MESSAGE_TYPE MESSAGE_TYPE}
- {@link #REPLY_STATUS REPLY_STATUS}
- {@link #SENDER_JOB_NAME SENDER_JOB_NAME}
- {@link #SENDER_USER_NAME SENDER_USER_NAME}
- {@link #SENDER_JOB_NUMBER SENDER_JOB_NUMBER}
- {@link #SENDING_PROGRAM_NAME SENDING_PROGRAM_NAME}
- {@link #SUBSTITUTION_DATA SUBSTITUTION_DATA}
Use any of these attribute IDs with
{@link com.ibm.as400.resource.Resource#getAttributeValue getAttributeValue()}
to access the attribute values for an RQueuedMessage.
// Create an RMessageQueue object to refer to a specific message queue.
AS400 system = new AS400("MYSYSTEM", "MYUSERID", "MYPASSWORD");
RMessageQueue messageQueue = new RMessageQueue(system, "/QSYS.LIB/MYLIB.LIB/MYMSGQ.MSGQ");
// Get the first RQueuedMessage from the RMessageQueue.
RQueuedMessage queuedMessage = messageQueue.resourceAt(0);
// Get the message text from the RQueuedMessage.
String messageText = (String)queuedMessage.getAttributeValue(RQueuedMessage.MESSAGE_TEXT);
@deprecated Use
{@link com.ibm.as400.access.QueuedMessage QueuedMessage} instead, as this package may be removed in the future.
