Member Function Documentation

◆ append_ports()

void AudioTrack::append_ports	(	std::vector< Port * > &	ports,
		bool	include_plugins ) const

finalvirtual

Appends all channel ports and optionally plugin ports to the array.

Implements Track.

◆ clear_objects()

void AudioTrack::clear_objects ( )

overridevirtual

Removes all objects recursively from the track.

Reimplemented from Track.

◆ fill_events()

void AudioTrack::fill_events	(	const EngineProcessTimeInfo &	time_nfo,
		std::pair< AudioPort &, AudioPort & >	stereo_ports )

Wrapper for audio tracks to fill in StereoPorts from the timeline data.

Note: The engine splits the cycle so transport loop related logic is not needed.

Parameters

stereo_ports StereoPorts to fill.

◆ get_regions_in_range()

void AudioTrack::get_regions_in_range	(	std::vector< Region * > &	regions,
		const Position *	p1,
		const Position *	p2 )

overridevirtual

Returns all the regions inside the given range, or all the regions if both p1 and p2 are NULL.

Returns: The number of regions returned.

Reimplemented from Track.

◆ init_after_cloning()

void AudioTrack::init_after_cloning	(	const AudioTrack &	other,
		ObjectCloneType	clone_type )

overridevirtual

Initializes the cloned object.

Note: Only final classes should implement this.

Exceptions

ZrythmException If the object could not be cloned.

Implements ICloneable< AudioTrack >.

◆ init_loaded()

void AudioTrack::init_loaded	(	PluginRegistry &	plugin_registry,
		PortRegistry &	port_registry )

overridevirtual

Adds additional metadata to track members after deserialization.

Note: Each implementor must chain up to its direct superclass.

Implements Track.

◆ validate()

bool AudioTrack::validate ( ) const

overridevirtual

Verifies the identifiers on a live Track (in the project, not a clone).

Returns: True if pass.

Implements Track.
