disconnect

public Observable<LifecycleState> disconnect()

Description copied from interface: Service

Disconnects all currently enabled Service Endpoints.

Specified by:

disconnect in interface Service

Returns:

the states of the Service after the disconnect process for all enabled Endpoints.

logIdent

protected static String logIdent(String hostname,
                                 Service service)

Simple log helper to give logs a common prefix.
