Class ChunkRenderLayerBackend

Base class for defining a SharedObject type that will never be owned.

Constructors

constructor

new ChunkRenderLayerBackend(rpc?: RPC, options?: any): ChunkRenderLayerBackend
Parameters
- Optional rpc: RPC
- options: any = {}
Returns ChunkRenderLayerBackend

Properties

RPC_TYPE_ID

RPC_TYPE_ID: string

Should be set to a constant specifying the SharedObject type identifier on the prototype of final derived owner classes. It is not used on counterpart (non-owner) classes.
