Channel SDK entity

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

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

Create a Channel

Use this factory method to return a local Channel SDK entity for a single channel. A Channel SDK entity centralizes common operations—such as subscribing and publishing—so you can prototype and build faster.

1pubnub.channel(name: String): Channel

* required

Parameter	Description
name * Type: String	Name of the channel for which to create the SDK entity.
