Detailed Description

This class is an interface for elements with duration, such as notes and rests.

It is not an abstract class but should not be instanciated directly.

Member Function Documentation

◆ GetInterfaceAlignmentDuration()

Fraction vrv::DurationInterface::GetInterfaceAlignmentDuration	(	int	num,
		int	numBase
	)		const

Returns the duration (in Fraction) for the element.

It returns 0/1 for grace notes. Careful: this method is not overriding LayerElement::GetAlignmentDuration since LayerElement and DurationInterface have no inheritance link.

◆ GetNoteOrChordDur()

data_DURATION vrv::DurationInterface::GetNoteOrChordDur ( const LayerElement * element ) const

If the element is part of a chord, return the chord actual duration, otherwise the note actual duration.

Since we need to check what the element is, we need to pass it as parameter.

◆ HasIdenticalDurationInterface()

bool vrv::DurationInterface::HasIdenticalDurationInterface ( const DurationInterface * otherDurationInterface ) const

Interface comparison operator.

Check if the LayerElement has a DurationInterface and compare attributes

◆ IsInterface()

InterfaceId vrv::DurationInterface::IsInterface ( ) const

inlineoverridevirtual

Virtual method returning the InterfaceId of the interface.

Needs to be overridden in child classes.

Reimplemented from vrv::Interface.

◆ Reset()

void vrv::DurationInterface::Reset ( )

overridevirtual

Virtual reset method.
