- range
- HttpRange
Specifies the range of bytes to be cleared. Both the start and end of the range must be specified. For a page clear operation, the page range can be up to the value of the blob's full size. Given that pages must be aligned with 512-byte boundaries, the start of the range must be a modulus of 512 and the end of the range must be a modulus of 512 – 1. Examples of valid byte ranges are 0-511, 512-1023, etc.
- conditions
- PageBlobRequestConditions
Optional PageBlobRequestConditions to add conditions on clearing pages from this page blob.
- cancellationToken
- CancellationToken
Optional CancellationToken to propagate notifications that the operation should be cancelled.
Returns
A Response<T> describing the state of the updated pages.
Remarks
A RequestFailedException will be thrown if a failure occurs.
