### findAll

LanguageCode) => PromiseFacetValue>>>`} />
### findAll

### findAll
\RequestContext | LanguageCode, lang?: LanguageCode) => PromiseFacetValue>>>`} />
### findAllList
\RequestContext, options?: ListQueryOptions<FacetValue>, relations?: RelationPaths<FacetValue>) => Promise<PaginatedListFacetValue>>>`} />
Returns a PaginatedList of FacetValues.
TODO: in v2 this should replace the `findAll()` method.
A separate method was created just to avoid a breaking change in v1.9.
### findOne
\RequestContext, id: ID) => PromiseFacetValue> | undefined>`} />
### findByIds
\RequestContext, ids: ID[]) => PromiseFacetValue>>>`} />
### findByFacetId
\RequestContext, id: ID) => PromiseFacetValue>>>`} />
Returns all FacetValues belonging to the Facet with the given id.
### findByFacetIdList
\RequestContext, id: ID, options?: ListQueryOptions<FacetValue>, relations?: RelationPaths<FacetValue>) => Promise<PaginatedListFacetValue>>>`} />
Returns all FacetValues belonging to the Facet with the given id.
### create

### delete

### checkFacetValueUsage
\RequestContext, facetValueIds: ID[], channelId?: ID) => Promise<{ productCount: number; variantCount: number }>`} />
Checks for usage of the given FacetValues in any Products or Variants, and returns the counts.
