subscribe

Start receiving events from the subscription (or subscriptions) represented by this object.

The PubNub client will start a network connection to the server if it doesn't have one already, or will alter the existing connection to add channels and groups requested by this subscription if needed.

Please note that passing a cursor to subscribe affects all subscriptions that are currently active in the com.pubnub.api.PubNub client, as it will reset the global timetoken for the server connection. If an active subscription had previously delivered any events to its listeners, it will only deliver events newer that the last timetoken it recorded.
