- action
- SequenceNumberAction
Specifies how the service should modify the blob's sequence number.
Max sets the sequence number to
be the higher of the value included with the request and the value
currently stored for the blob. Update
sets the sequence number to the sequenceNumber
value. Increment increments
the value of the sequence number by 1. If specifying
Increment, do not include the
sequenceNumber because that will throw a
RequestFailedException.
An updated sequence number of your choosing, if
action is Max
or Update. The value should
not be provided if action is
Increment. The sequence number
is a user-controlled property that you can use to track requests
and manage concurrency issues via PageBlobRequestConditions.
- conditions
- PageBlobRequestConditions
Optional PageBlobRequestConditions to add conditions on updating the sequence number of this page blob.
- cancellationToken
- CancellationToken
Optional CancellationToken to propagate notifications that the operation should be cancelled.
Returns
A Response<T> describing the updated page blob.
Remarks
A RequestFailedException will be thrown if a failure occurs.
