Interface IIdentity<TKey>

Namespace

SodaFlow.Collections

Assembly

SodaFlow.Core.Collections.dll

An optional short path for an identity that holds its own key. Use this interface, and the Create overloads of ReactiveCollection read the key from the identity, and a selector is not necessary.

[PublicAPI]
public interface IIdentity<out TKey> where TKey : notnull

Type Parameters

TKey

The type of the key this identity carries.

Extension Methods

MaybeExtensionMethods.ToMaybe<T>(T?)

UnitExtensionMethods.Ignore<T>(T)

UnitExtensionMethods.Upcast<T>(T)

Remarks

This interface is optional. The overloads with a selector on ReactiveCollection<TKey, TIdentity, TState> are the path for an identity type that cannot use an interface, or that must not use one. Examples are a record from a different assembly, and a record whose code calculates the key and does not hold it in a property.

Properties

Key

The key derived from this identity.
