Member Function Documentation

◆ getName()

juce::String getName ( ) const

overridevirtual

Implements ParameterAutomation.

◆ getParameterIndex()

int getParameterIndex ( ) const

overridevirtual

Implements ParameterAutomation.

◆ getParameterProperties()

juce::NamedValueSet & getParameterProperties ( )

overridevirtual

Implements ParameterAutomation.

◆ getNumSteps()

int getNumSteps ( ) const

overridevirtual

Implements ParameterAutomation.

◆ getAllValueStrings()

juce::StringArray getAllValueStrings ( ) const

overridevirtual

Implements ParameterAutomation.

◆ updateProcessor()

void updateProcessor ( double pts )

overridevirtual

This updates the parameter to match the state at a certain timepoint.

Call this before you process a block.

Implements ParameterAutomation.

References ParameterAutomation::gestureInProgress, and ParameterAutomation::getValueForTime().

◆ getRealValueForTime()

double getRealValueForTime ( double pts ) const

overridevirtual

Returns the unnormalised value at a certain time.

Implements ParameterAutomation.

References ParameterAutomation::getValueForTime().

◆ setRealValue() [1/2]

void setRealValue ( double value )

overridevirtual

Set the value from an unnormalised value.

Implements ParameterAutomation.

References ParameterAutomation::setValue().

◆ setRealValue() [2/2]

void setRealValue	(	double	pts,
		double	value
	)

overridevirtual

Set the value from an unnormalised value at a certain timepoint.

If there was no keyframe recorded yet, this will just call setValue. If there was a keyframe anywhere on the automation, this will add a keyframe at this position.

Implements ParameterAutomation.
