C1.LiveLinq.Indexing.Index-1
Index<T> Class
Base class for the Index<T, TKey> class.
Implements
Namespace: C1.LiveLinq.Indexing
Assembly: C1.LiveLinq.4.8.dll
Syntax
public abstract class Index<T> : IndexDefinition<T>, IIndexScanner<T>Type Parameters
| Name | Description |
|---|---|
| T | The type of the elements of the collection to index. |
Remarks
You don't typically use the Index<T> class directly. It provides functionality of the Index<T, TKey> class that does not depend on the index key type. The base class Index<T> is needed only if the index key type is not known, usually in general-purpose code intended for reuse with different key types.
Properties
| Name | Description |
|---|---|
| ItemCount | Gets the number of elements in the indexed collection. |
| KeyCount | Gets the number of distinct key values in all items of this collection. |
Methods
| Name | Description |
|---|---|
| ContainsKey(object) | Returns a value that indicates whether the indexed collection contains an item with the given key value. Implements IIndexScanner(T).ContainsKey(object) |
| Find(object) | Finds items with the specified key value. Implements IIndexScanner(T).Find(object) |
| FindBetween(object, bool, object, bool, Order) | Finds items with key values in the interval between the specified values. Implements IIndexScanner(T).FindBetween(object,bool,object,bool,Order) |
| FindGreater(object, bool, Order) | Finds items with keys greater than the specified value. |
| FindKeys(IEnumerable, Order) | Finds items containing any of the specified key values. Implements FindKeys(IEnumerable,Order) |
| FindLess(object, bool, Order) | Finds items with keys less than the specified value. Implements IIndexScanner(T).FindLess(object,bool,Order) |
| FindStartingWith(string, Func<string, bool>, Order) | Finds items with string key values starting with the specified string. Implements IIndexScanner(T).FindStartingWith(string,Func(string, bool),Order) |
| GroupJoin<T2, TResult>(IIndexScanner<T2>, Func<T, IEnumerable<T2>, TResult>) | Correlates the items of this indexed collection with the items of another indexed collection and groups the results by the item of this collection. Implements IIndexScanner(T).GroupJoin |
| GroupJoin<T2, TResult>(IEnumerable<T2>, Func<T2, object>, Func<IEnumerable<T>, T2, TResult>) | Correlates the items of this indexed collection with the items of another sequence and groups the results by the item of the second sequence. Implements IIndexScanner(T).GroupJoin |
| GroupJoin<T2, TResult>(IEnumerable<T2>, Func<T2, object>, Func<T, IEnumerable<T2>, TResult>) | Correlates the items of this indexed collection with the items of another sequence and groups the results by the item of this collection. Implements IIndexScanner(T).GroupJoin |
| Join<T2, TResult>(IIndexScanner<T2>, Func<T, T2, TResult>, JoinOperator) | Correlates the items of this indexed collection with the items of another indexed collection and returns the combined items with matching keys. Implements IIndexScanner(T).Join |
| Join<T2, TResult>(IEnumerable<T2>, Func<T2, object>, Func<T, T2, TResult>, JoinOperator) | Correlates the items of this indexed collection with the items of another sequence and returns the combined items with matching keys. Implements IIndexScanner(T).Join |
