java.lang.Object | +----com.ibm.mq.MQGetMessageOptions
This class contains options which control the behavior of MQQueue.get().
public MQGetMessageOptions();
Constructs an MQGetMessageOptions object with options set to MQC.MQGMO_MO_WAIT, a wait interval of zero, and a blank resolved queue name.
public MQGetMessageOptions(boolean noReadBack);
Constructs an MQGetMessageOptions object with an option on reading the options field. You can use this constructor to save some overheads if your application never needs to read back the options field.
public char
Whether the retrieved message is in a group, and if it is, whether it is the last in the group. Possible values are:
public int
Selection criteria which determine which message is retrieved. The following match options can be set:
The default value is MQC.MQMO_MATCH_MSG_ID | MQC.MQMO_MATCH_CORREL_ID .
public byte[]
A token for use when getting messages. It is set either by the queue manager or by the application in combination with MQMO_MATCH_MSG_TOKEN . The token is truncated if its size is greater than MQC.MQ_MSG_TOKEN_LENGTH. It is ignored if it has been set without the corresponding matchOption being set. If matchOption is set for a platform other than z/OS an attempted get will fail.
public int
Options which control the action of MQQueue.get() . Any or none of the following values can be specified. If more than one option is required the values can combined using either '+' or '|'.
public java.lang.String
The local name of the queue from which the message was retrieved. This is the resolved name as set by the queue manager. It is different from the name used to open the queue, if an alias queue or model queue was opened.
public int
The length in bytes of the message data. It is set by the queue manager to the value returned by the MQGET call. If the queue manager does not support this capability, the value is set to MQC.MQRL_UNDEFINED .
public char
Whether segmentation is allowed for the retrieved message. Possible values are:
public char
Whether the retrieved message is a segment of a logical message. If the message is a segment, indicates whether or not it is the last segment. Possible values are:
public int
The maximum time (in milliseconds) that an MQQueue.get() call waits for a suitable message to arrive. It is used in conjunction with MQC.MQGMO_WAIT. A value of MQC.MQWI_UNLIMITED indicates that an unlimited wait is required.
