Constructor & Destructor Documentation

◆ AudioParameterInt()

AudioParameterInt::AudioParameterInt	(	const String &	parameterID,
		const String &	parameterName,
		int	minValue,
		int	maxValue,
		int	defaultValue,
		const String &	parameterLabel = `String()`,
		std::function< String(int value, int maximumStringLength)>	stringFromInt = `nullptr`,
		std::function< int(const String &text)>	intFromString = `nullptr`
	)

Creates a AudioParameterInt with the specified parameters.

Parameters

parameterID	The parameter ID to use
parameterName	The parameter name to use
minValue	The minimum parameter value
maxValue	The maximum parameter value
defaultValue	The default value
parameterLabel	An optional label for the parameter's value
stringFromInt	An optional lambda function that converts a int value to a string with a maximum length. This may be used by hosts to display the parameter's value.
intFromString	An optional lambda function that parses a string and converts it into an int. Some hosts use this to allow users to type in parameter values.

◆ ~AudioParameterInt()

AudioParameterInt::~AudioParameterInt ( )

override

Destructor.

Member Function Documentation

◆ get()

int AudioParameterInt::get ( ) const

noexcept

Returns the parameter's current value as an integer.

References roundToInt().

◆ operator int()

AudioParameterInt::operator int ( ) const

noexcept

Returns the parameter's current value as an integer.

◆ operator=()

AudioParameterInt& AudioParameterInt::operator= ( int newValue )

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

The value passed in will be snapped to the permitted range before being used.

◆ getRange()

Range<int> AudioParameterInt::getRange ( ) const

noexcept

Returns the parameter's range.

References NormalisableRange< ValueType >::end, RangedAudioParameter::getNormalisableRange(), int(), and NormalisableRange< ValueType >::start.

◆ getNormalisableRange()

const NormalisableRange<float>& AudioParameterInt::getNormalisableRange ( ) const

overridevirtual

Returns the range of values that the parameter can take.

Implements RangedAudioParameter.

◆ valueChanged()

virtual void AudioParameterInt::valueChanged ( int newValue )

protectedvirtual

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