UserMetadata Entity
Since version 9.0.0, the java SDK supports entities, which are SDK objects that provide operations on endpoints associated with their type. They are designed as first-class citizens to facilitate working with various PubNub APIs.
Certain PubNub API functionality is already exposed via entities, while other may still be available using the pubnub
object.
