Selector

public class Selector<State, Value> : SelectorProtocol

A type which takes a State and returns a Value from it.

Selectors can be based on other Selectors making it possible to select a combined Value.

Declaration
Swift

public let id: UUID
init(keyPath:)
Creates a Selector from a keyPath.
Declaration
Swift

public convenience init(keyPath: KeyPath<State, Value>)
Parameters

keyPath

The keyPath to create the Selector from
init(projector:)
Creates a Selector from a projector closure.
Declaration
Swift

public init(projector: @escaping (State) -> Value)
Parameters

projector

The projector closure to create the Selector from
