Agora provides interactive whiteboard with high reliability and rich features though a virtual global network and flexible combinations of APIs.

The WhiteSdk class provides the main methods for initializing the WhiteSdk instance and joining the live Interactive Whiteboard room.
The Room class provides methods that manage the live Interactive Whiteboard room.
The Displayer is the parent class of the Room class. The Room class can inherit the methods of the Displayer class.
