User selectors
User selectors have values that are
zero or positive. For the administration of MQSeries(R) objects, valid user selectors are
already defined by the following constants:
- MQCA_* and MQIA_* (object attributes)
- MQCACF_* and MQIACF_* (items relating specifically to PCF)
- MQCACH_* and MQIACH_* (channel attributes)
For user messages, the meaning of a user selector is defined by the application.
The following additional user selectors are introduced by the MQAI:
- MQIACF_INQUIRY
- Identifies an WebSphere MQ object attribute to be returned by an Inquire command.
- MQHA_BAG_HANDLE
- Identifies a bag handle residing within another bag.
- MQHA_FIRST
- Lower limit for handle selectors.
- MQHA_LAST
- Upper limit for handle selectors.
- MQHA_LAST_USED
- Upper limit for last handle selector allocated.
- MQCA_USER_LIST
- Default user selector. Supported on Visual Basic only. This selector
supports character type and represents the default value used if the Selector parameter is omitted on the mqAdd*, mqSet*,
or mqInquire* calls.
- MQIA_USER_LIST
- Default user selector. Supported on Visual Basic only. This selector
supports integer type and represents the default value used if the Selector parameter is omitted on the mqAdd*, mqSet*,
or mqInquire* calls.
