Interface CoreFacet

The Facet headless controller offers a high-level interface for designing a common facet UI controller.

interface CoreFacet {
    state: CoreFacetState;
    deselectAll(): void;
    disable(): void;
    enable(): void;
    isSortedBy(criterion: FacetSortCriterion): boolean;
    isValueExcluded(value: FacetValue): boolean;
    isValueSelected(value: FacetValue): boolean;
    showLessValues(): void;
    showMoreValues(): void;
    sortBy(criterion: FacetSortCriterion): void;
    subscribe(listener: () => void): Unsubscribe;
    toggleExclude(selection: FacetValue): void;
    toggleSelect(selection: FacetValue): void;
    toggleSingleExclude(selection: FacetValue): void;
    toggleSingleSelect(selection: FacetValue): void;
}
