provider: HierarchyProvider<TNode>

Methods

[AsyncOrderedIterable.thenByAsync](keySelector, comparison, descending)

Declaration

[AsyncOrderedIterable.thenByAsync]<K>(keySelector: (element: T) => K, comparison: Comparison<K> | Comparer<K>, descending: boolean): AsyncOrderedHierarchyIterable<TNode, T>;

Type Parameters

K

Parameters

keySelector: (element: T) => K

comparison: Comparison<K> | Comparer<K>

descending: boolean

Returns

AsyncOrderedHierarchyIterable<TNode, T>

thenBy(keySelector, comparison)

Creates a subsequent ordered subquery whose elements are sorted in ascending order by the provided key.

Declaration

thenBy<K>(keySelector: (element: T) => K, comparison?: Comparison<K> | Comparer<K>): AsyncOrderedHierarchyQuery<TNode, T>;

Type Parameters

K

Parameters

keySelector: (element: T) => K

A callback used to select the key for an element.

comparison: Comparison<K> | Comparer<K>

An optional callback used to compare two keys. Order

Returns

AsyncOrderedHierarchyQuery<TNode, T>

thenByDescending(keySelector, comparison)

Creates a subsequent ordered subquery whose elements are sorted in descending order by the provided key.

Declaration

thenByDescending<K>(keySelector: (element: T) => K, comparison?: Comparison<K> | Comparer<K>): AsyncOrderedHierarchyQuery<TNode, T>;

Type Parameters

K

Parameters

keySelector: (element: T) => K

A callback used to select the key for an element.

comparison: Comparison<K> | Comparer<K>

An optional callback used to compare two keys. Order

Returns

AsyncOrderedHierarchyQuery<TNode, T>
