GroupingQuery<TKey, T> Class

Represents a collection of IndexedGroup<TKey, T>, groups of elements with the same key, resulting from a search operation with grouping.

Inheritance

object

GroupingQuery<TKey, T>

Implements

IEnumerable<IndexedGroup<TKey, T>>

IEnumerable

Namespace: C1.LiveLinq.Indexing.Search

Assembly: C1.LiveLinq.4.8.dll

Syntax

public abstract class GroupingQuery<TKey, T> : IEnumerable<IndexedGroup<TKey, T>>, IEnumerable

Public MustInherit Class GroupingQuery(Of TKey, T)
    Implements IEnumerable(Of IndexedGroup(Of TKey, T)), IEnumerable

Type Parameters

Name	Description
TKey	The type of the index key.
T	The type of the elements of the indexed collection.

Remarks

The result of any index search operation, IndexQuery<T, TKey> can be grouped by applying GroupByKey(). It is grouped by the key that was used to perform the search operation. For example,

customers.Indexes(c => c.City).All().GroupByKey();
customers.Indexes(c => c.City).FindBetween("A", "Z").GroupByKey();

Methods

Name	Description
GetEnumerator()	Returns an enumerator that iterates through the GroupingQuery<TKey, T>.
