Service
Description
closeLatch
Closes the latch for the specified canonical ID, application ID (appId), and object type (objectId). To close the latch, the isLatchClosed field of the cross‑reference table is set to true. A closed latch indicates that the resource described in the cross‑reference row cannot be acted upon until the latch is open using the openLatch service.
isLatchClosed
Determines whether the latch is open or closed for the specified canonical ID, application ID (appId), and object type (objectId). To check the status of the latch, the service uses the isLatchClosed field of the cross‑reference table. The output provides a status of true (the latch is closed) or false (the latch is open).
openLatch
Opens the latch for the specified canonical ID, application ID (appId), and object type (objectId). To open the latch, the isLatchClosed field of the cross‑reference table is set to false. An open latch indicates that the resource described in the cross‑reference row can be acted upon.
