  5. def add(key: String, flags: Int, expiry: Time, value: Buf): Future[Boolean]

    Store a key but only if it doesn't already exist on the server.

    Store a key but only if it doesn't already exist on the server.

    flags is an arbitrary integer that the server stores along with the data and sends back when the item is retrieved. Clients may use this as a bit field to store data-specific information; this field is opaque to the server.

    expiry is the expiration time for entries. If it is Time.epoch, Time.Top, Time.Bottom or Time.Undefined then the item never expires, although it may be deleted from the cache to make room for other items. This is also the case for values where the number of seconds is larger than Long.MaxValue. Otherwise, clients will not be able to retrieve this item after the expiration time arrives (measured on the cache server).

    returns

    true if stored, false if not stored

  11. def checkAndSet(key: String, flags: Int, expiry: Time, value: Buf, casUnique: Buf): Future[CasResult]

    Perform a CAS operation on the key, only if the value has not changed since the value was last retrieved, and casUnique extracted from a gets command. We treat the "cas unique" token opaquely, but in reality it is a string-encoded u64.

  12. def checkAndSet(key: String, value: Buf, casUnique: Buf): Future[CasResult]

    Perform a CAS operation on the key, only if the value has not changed since the value was last retrieved.

    Perform a CAS operation on the key, only if the value has not changed since the value was last retrieved. This is enforced by passing a casUnique token extracted from a gets command. If the casUnique token matches the one on the server, the value is replaced. We treat the "cas unique" token opaquely, but in reality it is a string-encoded u64.

    Neither flags nor expiry are supplied.

    returns

    Stored if the operation was successful, Exists if the operation failed because someone else had changed the value, or NotFound if the key was not found in the cache.
