Parameters
- source
The URI of a source blob.
- sourceAccessCondition
An object that represents the access conditions for the source blob. If
null, no condition is used.
- destAccessCondition
An object that represents the access conditions for the destination blob. If
null, no condition is used.
- options
A BlobRequestOptions object that specifies additional options for the request.
- operationContext
An OperationContext object that represents the context for the current operation.
Return Value
The copy ID associated with the copy operation.Remarks
This method fetches the blob's ETag, last modified time, and part of the copy state. The copy ID and copy status fields are fetched, and the rest of the copy state is cleared.
