Properties

hasLoadedData

hasLoadedData: () => boolean & () => boolean

Returns true. Provided for consistency with async data loader

invalidateChildrenIds

invalidateChildrenIds: (optimistic?: boolean) => Promise<void>

Invalidate fetched children ids for item, and triggers a refetch and subsequent rerender if the item is visible

---

Type declaration

• • (optimistic?: boolean): Promise<void>

  • Parameters

    • optionaloptimistic: boolean

      If true, the item will not trigger a state update on loadingItemChildrens, and the tree will continue to display the old data until the new data has loaded.

    Returns Promise<void>

invalidateItemData

invalidateItemData: (optimistic?: boolean) => Promise<void>

Invalidate fetched data for item, and triggers a refetch and subsequent rerender if the item is visible

---

Type declaration

• • (optimistic?: boolean): Promise<void>

  • Parameters

    • optionaloptimistic: boolean

      If true, the item will not trigger a state update on loadingItemData, and the tree will continue to display the old data until the new data has loaded.

    Returns Promise<void>

isLoading

isLoading: () => boolean & () => boolean

Returns false. Provided for consistency with async data loader

updateCachedChildrenIds

updateCachedChildrenIds: (childrenIds: string[], skipUpdateTree?: boolean) => void

Type declaration

• • (childrenIds: string[], skipUpdateTree?: boolean): void

  • Parameters

    • childrenIds: string[]

    • optionalskipUpdateTree: boolean

      If true, the tree will not rebuild the tree structure cache afterwards by calling tree.rebuildTree().

    Returns void

updateCachedData

updateCachedData: (data: undefined | T, skipUpdateTree?: boolean) => void

Set to undefined to clear cache without triggering automatic refetch. Use

@invalidateItemData

to clear and triggering refetch.

---

Type declaration

• • (data: undefined | T, skipUpdateTree?: boolean): void

  • Parameters

    • data: undefined | T

    • optionalskipUpdateTree: boolean

      If true, the tree will not rebuild the tree structure cache afterwards by calling tree.rebuildTree().

    Returns void
