bool IsEmpty ()

Returns whether no field is set.

bool HasUnknownData ()

Returns whether the table references unknown fields.

::fidl::WireTableBuilder< ::fuchsia_hardware_audio_signalprocessing::wire::EqualizerBandState> Builder (::fidl::AnyArena & arena)

Return a builder that by defaults allocates of an arena.

::fidl::WireTableExternalBuilder< ::fuchsia_hardware_audio_signalprocessing::wire::EqualizerBandState> ExternalBuilder (::fidl::ObjectView< ::fidl::WireTableFrame< ::fuchsia_hardware_audio_signalprocessing::wire::EqualizerBandState>> frame)

Return a builder that relies on explicitly allocating |fidl::ObjectView|s.

uint64_t & id ()

Unique ID for the band. Must match one of the `id`s specified in `Equalizer` `bands`.

Required.

bool has_id ()

::fuchsia_hardware_audio_signalprocessing::wire::EqualizerBandType & type ()

Type of band.

Required.

If this is a call to `SetElementState`, then the corresponding `SUPPORTS_TYPE_...`

`EqualizerSupportedControls` bit for `type` must be set in `Element.supported_controls`.

bool has_type ()

uint32_t & frequency ()

Center frequency for the band.

Required.

If this is a call to `SetElementState` and represents a change in this band's frequency,

then `CAN_CONTROL_FREQUENCY` must be set in `Element.supported_controls`.

bool has_frequency ()

float & q ()

Quality factor, usually denoted as "Q".

Indicates how narrow the frequency transition is. Higher Q values imply narrower

notches/peaks and steeper cuts/shelves. Must be positive.

Optional.

If used in `SetElementState` and represents a change in this band's q, then `CAN_CONTROL_Q`

must be set in `Element.supported_controls`. Must be finite.

bool has_q ()

float & gain_db ()

Gain in dB.

Required, for `EqualizerBandType` of `PEAK`, `LOW_SHELF` and `HIGH_SHELF`. Must be finite.

Disallowed, for `EqualizerBandType` of `NOTCH`, `LOW_CUT` and `HIGH_CUT`.

bool has_gain_db ()

bool & enabled ()

Enable/disable the band.

If disabled, audio still flows through the equalizer but this band has no effect.

If absent in the return value from `WatchElementState`, the band is enabled.

If omitted in a `SetElementState` call, the band's enable/disable state is unchanged.

Bypassing the entire enclosing processing element (by setting `ElementState.bypassed` to

true) does not change this field's value, although for an equalizer band to be functional,

its enclosing equalizer processing element must be both started and not bypassed.

Optional.

void EqualizerBandState (::fidl::AnyArena & allocator)

void EqualizerBandState (::fidl::ObjectView< ::fidl::WireTableFrame< ::fuchsia_hardware_audio_signalprocessing::wire::EqualizerBandState>> && frame)

This constructor allows a user controlled allocation (not using a Arena).

It should only be used when performance is key.

As soon as the frame is given to the table, it must not be used directly or for another table.
