Metadata about this
Trait
.Declaration
Swift
let metadata: TraitMetadata
-
List of attributes for the
ChannelTrait
.Declaration
Swift
let attributes: Matter.ChannelTrait.Attributes
-
Creates a new Trait instance using data read from the given
TraitDecoder
.Throws
HomeError.parseError
when parsing fails.Declaration
Swift
init(decoder: TraitDecoder, interactionProxy: (any InteractionProxy)?, metadata: TraitMetadata) throws
Parameters
decoder
The raw data representing this Trait.
interactionProxy
Proxy to the Interaction Client.
metadata
Metadata about this Trait.
-
Writes this object to the given
TraitEncoder
. ThrowsHomeError.encodingFailed
if the data could not be encoded.Declaration
Swift
func encode(with encoder: TraitEncoder) throws
-
This API provides the ability to invalidate state retrieved through subscriptions to the target device in the cases where state is not being reported correctly, either intentionally (e.g attributes in Matter traits with the “C” quality) or unintentionally due to poor implementations.
When successful, this API will result in a forced read of the convening scope as specified by the sub-class and return the result through existing Trait subscriptions if present and active.
This API is to be used sparingly as it can impact the performance and battery life of the target device. As such, this API may be throttled by the platform. Callers SHALL be prepared to deal with
HomeError
s thrown by this call.Declaration
Swift
func forceRead() async throws

Attributes for the
ChannelTrait
.Declaration
Swift
struct Attributes
-
Returns a Boolean value indicating whether two values are equal.
Equality is the inverse of inequality. For any values
a
andb
,a == b
implies thata != b
isfalse
.Parameters
lhs
A value to compare.
rhs
Another value to compare.
-
Hashes the essential components of this value by feeding them into the given hasher.
Implement this method to conform to the
Hashable
protocol. The components used for hashing must be the same as the components compared in your type’s==
operator implementation. Callhasher.combine(_:)
with each of these components.Important
In your implementation of
hash(into:)
, don’t callfinalize()
on thehasher
instance provided, or replace it with a different instance. Doing so may become a compile-time error in the future.Declaration
Swift
func hash(into hasher: inout Hasher)

-
Change the channel to the specified channel.
Declaration
Swift
func changeChannel(match: String) async throws -> Matter.ChannelTrait.ChangeChannelCommandResponse
Parameters
match
A string used to identify the intended channel, which may be a call sign, a name, or a number.
Return Value

command for this trait.Declaration
Swift
var supportsSkipChannelCommand: Bool { get }

Provides channel up and channel down functionality, by allowing the index of the selected channel to jump by the specified number of steps.
Declaration
Swift
func skipChannel(count: Int16) async throws
Parameters
count
When positive,
count
specifies the number of steps to increase the current channel number. When negative, it specifies the number of steps to decrease the current channel number. -
