@get

Get a number of values from the cache.

If you specify a non-zero value for expiration, the server will update the expiration value on the item (refer to the documentation on cmd_store to see the meaning of the expiration). All other members should be set to zero.

Example:

  GetCommand gc = GetCommand() {
      key = "my-key"
  };
  // Set an expiration of 60 (optional)
  gc.exptime = 60;
  GetCommand*[] commands = { &gc };
  instance.get( null, commands );

It is possible to get an item with a lock that has a timeout. It can then be unlocked with either a CAS operation or with an explicit unlock command.

You may specify the expiration value for the lock in the expiration (setting it to 0 cause the server to use the default value).

Parameters:

command_cookie	A cookie passed to all of the notifications from this command
commands	the array containing the items to get

Returns:

The status of the operation
