Abstract Value Members

  1. abstract def add(key: String, flags: Int, expiry: Time, value: T): 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.

    returns

    true if stored, false if not stored

  2. abstract def append(key: String, flags: Int, expiry: Time, value: T): Future[Boolean]

    Append bytes to the end of an existing key.

    Append bytes to the end of an existing key. If the key doesn't exist, the operation has no effect.

    returns

    true if stored, false if not stored

  3. abstract def cas(key: String, flags: Int, expiry: Time, value: T, casUnique: ChannelBuffer): Future[Boolean]

    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.

    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.

    returns

    true if replaced, false if not

  4. abstract def channelBufferToType(a: ChannelBuffer): T

  5. abstract def decr(key: String, delta: Long): Future[Option[Long]]

    Decrement a key.

    Decrement a key. Interpret the value as an JLong if it is parsable. This operation has no effect if there is no value there already.

  6. abstract def delete(key: String): Future[Boolean]

    Remove a key.

    Remove a key.

    returns

    true if deleted, false if not found

  7. abstract def getResult(keys: Iterable[String]): Future[GetResult]

    Get a set of keys from the server.

  8. abstract def getsResult(keys: Iterable[String]): Future[GetsResult]

    Get a set of keys from the server.

    Get a set of keys from the server. Returns a Future[GetsResult] that encapsulates hits, misses and failures. This variant includes the casToken from memcached.

  9. abstract def incr(key: String, delta: Long): Future[Option[Long]]

    Increment a key.

    Increment a key. Interpret the value as an Long if it is parsable. This operation has no effect if there is no value there already.

  10. abstract def prepend(key: String, flags: Int, expiry: Time, value: T): Future[Boolean]

    Prepend bytes to the beginning of an existing key.

    Prepend bytes to the beginning of an existing key. If the key doesn't exist, the operation has no effect.

    returns

    true if stored, false if not stored

  11. abstract def release(): Unit

    release the underlying service(s)

  12. abstract def replace(key: String, flags: Int, expiry: Time, value: T): Future[Boolean]

    Replace bytes on an existing key.

    Replace bytes on an existing key. If the key doesn't exist, the operation has no effect.

    returns

    true if stored, false if not stored

  13. abstract def set(key: String, flags: Int, expiry: Time, value: T): Future[Unit]

    Store a key.

    Store a key. Override an existing value.

    returns

    true

  14. abstract def stats(args: Option[String]): Future[Seq[String]]

    Send a stats command with optional arguments to the server

    Send a stats command with optional arguments to the server

    returns

    a sequence of strings, each of which is a line of output
