StaticMethod DeleteDatasetCopy (LibOpt_SnapshotReplannableCopyDataset snapshot)
|
{
|
Description:
|
[*
|
This method deletes the dataset that is attached to the `snapshot` variable.
|
If the dataset is still being created, then it is not possible to delete the dataset yet. In this case, the `snapshot.HasToBeDeleted` flag is set to `true`.
|
By setting this flag, the `LibOpt_DatasetCopyConditional::HandleSuccessfulDatasetCopy` method will automatically delete the dataset after the dataset has been created.
