How to use the @pixi/loaders.LoaderResource.TYPE function in @pixi/loaders

static use(resource, next)
    {
        // skip if no data or not xml data
        if (!resource.data || resource.type !== LoaderResource.TYPE.XML)
        {
            next();

            return;
        }

        // skip if not bitmap font data, using some silly duck-typing
        if (resource.data.getElementsByTagName('page').length === 0
            || resource.data.getElementsByTagName('info').length === 0
            || resource.data.getElementsByTagName('info')[0].getAttribute('face') === null
        )
        {
            next();

            return;
        }

static use(resource, next)
    {
        const imageResourceName = `${resource.name}_image`;

        // skip if no data, its not json, it isn't spritesheet data, or the image resource already exists
        if (!resource.data
            || resource.type !== LoaderResource.TYPE.JSON
            || !resource.data.frames
            || this.resources[imageResourceName]
        )
        {
            next();

            return;
        }

        const loadOptions = {
            crossOrigin: resource.crossOrigin,
            metadata: resource.metadata.imageMetadata,
            parentResource: resource,
        };

        const resourcePath = SpritesheetLoader.getResourcePath(resource, this.baseUrl);
