Action 

struct Action
 
extension Action : Copyable, CustomStringConvertible, Equatable, Escapable, Hashable, Identifiable, Node, Sendable

Base struct for all Actions in the automation graph.

  • id

    The stable identity of the entity associated with this instance.

    Declaration

    Swift

    let id: String

  • The behavior to take when the Action is executed.

    Declaration

    Swift

    let behavior: any ActionBehavior

  • An expression that specifies an entity or a list of entities associated with the Action at runtime.

    When entityExpression represents a single entity, entityExpression will be Constant(value: AnyAutomationEntity). Otherwise, entityExpression is an Expression, capable of resolving to any number of entities.

    Declaration

    Swift

    let entityExpression: any Expression

  • The unique ID for the entity associated with the Action.

    entity will be nil if the init(entityExpression: …) was used and the entityExpression is not a Constant to an AnyAutomationEntity.

    Declaration

    Swift

    var entity: (any HomeObject)? { get }

  • For device entities, the identifier of the DeviceType associated with the action.

    deviceType will be nil if entity is nil or not a device, such as a Structure or Room.

    Declaration

    Swift

    var deviceType: (any DeviceType.Type)? { get }

  • For device entities, the string-based identifier for the DeviceType. If the deviceType is UnknownDeviceType it will refer to the original DeviceType ID provided.

    deviceTypeID will be nil if entity is nil or not a device, such as a Structure or Room.

    Declaration

    Swift

    var deviceTypeID: String? { get }

  • Returns a Boolean value indicating whether two values are equal.

    Equality is the inverse of inequality. For any values a and b, a == b implies that a != b is false.

    Declaration

    Swift

    static func == (lhs: Action, rhs: Action) -> Bool

    Parameters

    lhs

    A value to compare.
    rhs

    Another value to compare.

  • Returns true if the nodes are equal, false otherwise.

    Declaration

    Swift

    func isEqual(to other: any Node) -> Bool

  • A textual representation of this instance.

    Calling this property directly is discouraged. Instead, convert an instance of any type to a string by using the String(describing:) initializer. This initializer works with any type, and uses the custom description property for types that conform to CustomStringConvertible:

    struct Point: CustomStringConvertible {
    let x: Int, y: Int

    var description: String {
        return "(\(x), \(y))"
    }
}

let p = Point(x: 21, y: 30)
let s = String(describing: p)
print(s)
// Prints "(21, 30)"

    The conversion of p to a string in the assignment to s uses the Point type’s description property.

    Declaration

    Swift

    var description: String { get }
