Interface: SetVector¶
A value update to an already-defined property (device -> client).
Properties¶
state_present?¶
optionalstate_present?:boolean
Whether the wire message actually carried a state.
state is #IMPLIED on every set*Vector (white paper p.7) and means "no
change if absent", so a set without one must leave the cached state
alone. The vector's own state is never absent - the parser fills it with
the model default - which is why the fact rides on the message instead, as
SetVector.state_present does on the Python side. Absent here (an older
bridge, or a frame built by hand) means the state was carried.
