cas()

auto cas ( couchbase::cas cas ) -> append_options&

inline

Specifies a CAS value that will be taken into account on the server side for optimistic concurrency.

The CAS value is an opaque identifier which is associated with a specific state of the document on the server. The CAS value is received on read operations (or after mutations) and can be used during a subsequent mutation to make sure that the document has not been modified in the meantime.

If document on the server has been modified in the meantime the SDK will raise a errc::common::cas_mismatch. In this case the caller is expected to re-do the whole "fetch-modify-update" cycle again. Please refer to the SDK documentation for more information on CAS mismatches and subsequent retries.

Parameters

cas	the opaque CAS identifier to use for this operation.

Returns

the append_options for chaining purposes.
