Interface IResource

A resource is an item referenced elsewhere with the application. This will track when a resource is no longer being used and can be removed.

interface IResource {
    isIResource: true;
    addReference(ref: any): void;
    addUnloadListener(listener: IUnloadListener): void;
    deleteReference(ref: any): void;
    getName(): string;
    getType(): Promise<string>;
    isClosed(): boolean;
    toBuffer(): Promise<ArrayBuffer>;
    toJSONAsync(): Promise<JSON>;
}
