Examples of com.datastax.driver.core.Cluster$Manager

com.datastax.driver.core.Cluster
The sessions and hosts managed by this a Cluster instance.
Note: the reason we create a Manager object separate from Cluster is that Manager is not publicly visible. For instance, we wouldn't want user to be able to call the {@link #onUp} and {@link #onDown} methods.
