Instance Method Details

#alive? ⇒ Boolean

Returns whether the connection to the server is alive.

It is useful to call this method before making a call to the server that would change data on the server.

Note: This method is only useful if the server closed the connection or if a previous connection failure occurred. If the server is hard killed this will still return true until one or more writes are attempted.

Returns:

  • (Boolean)
