ChannelMetadata Entity

As of version 9.0.0, the Java software development kit (SDK) supports entities. Entities are SDK objects that bundle operations for a specific resource type and simplify working with PubNub application programming interfaces (APIs).

Use entities to perform common tasks without manually wiring requests. Some PubNub APIs are exposed via entities. Other operations remain available on the pubnub object.
