Constructor & Destructor Documentation

◆ AudioParameterBool()

AudioParameterBool::AudioParameterBool ( const String parameterID,
const String parameterName,
bool  defaultValue,
const String parameterLabel = String(),
std::function< String(bool value, int maximumStringLength)>  stringFromBool = nullptr,
std::function< bool(const String &text)>  boolFromString = nullptr 
)

Creates a AudioParameterBool with the specified parameters.

Parameters
parameterIDThe parameter ID to use
parameterNameThe parameter name to use
defaultValueThe default value
parameterLabelAn optional label for the parameter's value
stringFromBoolAn optional lambda function that converts a bool value to a string with a maximum length. This may be used by hosts to display the parameter's value.
boolFromStringAn optional lambda function that parses a string and converts it into a bool value. Some hosts use this to allow users to type in parameter values.

◆ ~AudioParameterBool()

AudioParameterBool::~AudioParameterBool ( )
override

Destructor.

Member Function Documentation

◆ get()

bool AudioParameterBool::get ( ) const
noexcept

Returns the parameter's current boolean value.

◆ operator bool()

AudioParameterBool::operator bool ( ) const
noexcept

Returns the parameter's current boolean value.

References dsp::get().

◆ operator=()

AudioParameterBool& AudioParameterBool::operator= ( bool  newValue)

Changes the parameter's current value to a new boolean.

◆ getNormalisableRange()

const NormalisableRange<float>& AudioParameterBool::getNormalisableRange ( ) const
overridevirtual

Returns the range of values that the parameter can take.

Implements RangedAudioParameter.

◆ valueChanged()

virtual void AudioParameterBool::valueChanged ( bool  newValue)
protectedvirtual

Override this method if you are interested in receiving callbacks when the parameter value changes.
