Class Item<TIdentity, TState>

Namespace

SodaFlow.Collections

Assembly

SodaFlow.Core.Collections.dll

An item in the collection, in two parts: the immutable part ( Identity) and the mutable part (State).

[PublicAPI]
public sealed class Item<TIdentity, TState> where TIdentity : notnull

Type Parameters

TIdentity

The type of the immutable part.

TState

The type of the mutable part.

Inheritance

object

Item<TIdentity, TState>

Inherited Members

object.Equals(object)

object.Equals(object, object)

object.GetHashCode()

object.GetType()

object.ReferenceEquals(object, object)

object.ToString()

Extension Methods

MaybeExtensionMethods.ToMaybe<T>(T?)

UnitExtensionMethods.Ignore<T>(T)

UnitExtensionMethods.Upcast<T>(T)

Remarks

The key comes from Identity only. No code in the update path can read Identity, because an update holds only a Func<TState, TState>. Thus, the structure keeps each key constant, and no test at run time is necessary. A change to an identity is a removal and then an add, which is a structural edit.

Constructors

Item(TIdentity, TState)

Creates an item from its two halves.

Properties

Identity

The immutable part, which gives the key.

State

The mutable part.
