struct

Matter::InteractionModel::AttributePath

Inherits TLV::Serializable < Struct < Value < Object

Attribute path identifying a specific attribute Encoded as a TLV list per Matter spec (and matter.js/CHIP encodings), and TLV::Serializable decoding is tolerant of list/structure variations. Note: fixed_size: true ensures proper type widths for iOS compatibility.

Matter spec allows Boolean true as a wildcard indicator for path fields. iOS/Apple controllers send true instead of omitting fields for wildcards. We handle this by accepting Bool in the union type and converting to nil.

Setters for API compatibility

endpoint_raw

Internal storage accepts Bool for wildcard indicator from iOS

endpoint_raw=(endpoint_raw : UInt16 | Bool | Nil)

Internal storage accepts Bool for wildcard indicator from iOS

list_index=(value : UInt16 | Nil)

list_index_raw

list_index_raw=(list_index_raw : UInt16 | Bool | Nil)

node

to_io(io : IO, format : IO::ByteFormat = IO::ByteFormat::LittleEndian) : Nil

to_s

Returns a nicely readable and concise string representation of this object, typically intended for users.

This method should usually not be overridden. It delegates to #to_s(IO) which can be overridden for custom implementations.

Also see #inspect.

to_slice

to_tlv(outer_tag : Nil | UInt8 | Tuple(UInt16, UInt16) | Tuple(UInt16, UInt16, UInt16) = nil) : TLV::Any

wildcard?

Wildcard path matches all endpoints/clusters/attributes

wildcard_path_flags

wildcard_path_flags=(value : UInt32 | Nil)

wildcard_path_flags_raw

wildcard_path_flags_raw=(wildcard_path_flags_raw : UInt32 | Nil)
