isConnected() on interface level

[nklasens]

It would be nice to have a way to check if the JRedis interfaces are connected to the server. I am implementing consistent hashing over multiple servers, but I don't have a way in the client to check if the server is present. I extended some classes now to delegate to org.jredis.ri.alphazero.connection.ConnectionBase.isConnected(), but it would be nice if that is already in jredis itself

The semantics of a on-demand connector are somewhat problematic and its not clear what is gained. (See response to your other comment). There is also 0 information gain in using jredis.isConnect() vs jredis.ping().
