Example 96 with BlockSnapshot

use of com.emc.storageos.db.client.model.BlockSnapshot in project coprhd-controller by CoprHD.

the class BlockSnapshotDeleteCompleter method createCompleter.

/**
 * This method is for creating the BlockSnapshotDeleteCompleter. This a bit unique from
 * the other completers because of the way that we need to complete the task. For the
 * case of CG snapshots, there will be multiple BlockSnapshots associated, even though
 * the request to delete the snapshot was against only one of the CG snaps. Here we will
 * make sure that the task completer has references to all the CG snaps, so that they
 * can be referred to in the completer. Main reason is that if a BlockSnapshot is marked
 * inactive, it can no longer be retrieved using AltIndex queries.
 *
 * @param dbClient [in] - DbClient for querying ViPR DB
 * @param snapshot [in] - BlockSnapshot object
 * @param task [in] - Task UUID for the snapshot delete operation
 * @return a new BlockSnapshotDeleteCompleter object
