public enum TraitValueKind

What sort of value a Trait carries, and therefore which TraitValue getter is the one that works.

There is deliberately no TLV

HomeKit characteristics can carry TLV8 blobs, which is how accessory vendors ship extensions outside the published characteristic set. Those have no portable meaning – decoding one requires the vendor’s own schema, and there is nothing on the Matter side to map them to. Exposing a byte array here would look like a capability and be an invitation to write iOS-only code inside a cross-platform API. A trait whose platform value is TLV8 is simply not in the Trait table.

Enum constants

`BOOLEAN`	True or false.
`INT`	A whole number with no unit.
`DOUBLE`	A measured quantity with a `TraitUnit`.
`STRING`	Free text.
`ENUM`	One of a fixed set, carried as an ordinal into one of this package’s domain enums – `LockState`, `HeatingCoolingMode`, `AirQualityLevel` and the rest.

Methods

`public static` `TraitValueKind[] values()`
`public static` `TraitValueKind valueOf(String name)`

Enum constant details

BOOLEAN

BOOLEAN

True or false. Read with TraitValue.getBoolean().

INT

INT

A whole number with no unit. Read with TraitValue.getInt().

DOUBLE

DOUBLE

A measured quantity with a TraitUnit. Read with TraitValue.getDouble(TraitUnit), which makes you name the unit you expect.

STRING

STRING

Free text. Read with TraitValue.getString().

ENUM

ENUM

One of a fixed set, carried as an ordinal into one of this package’s domain enums – LockState, HeatingCoolingMode, AirQualityLevel and the rest. Read it through that enum’s own lookup rather than through TraitValue.getEnumOrdinal(), which exists for the codec.
