Constructor & Destructor Documentation

◆ LoopInfo() [1/5]

tracktion::engine::LoopInfo::LoopInfo ( Engine & )

Creates an empty LoopInfo.

◆ LoopInfo() [2/5]

tracktion::engine::LoopInfo::LoopInfo ( const LoopInfo & )

Creates a copy of another LoopInfo.

◆ LoopInfo() [3/5]

tracktion::engine::LoopInfo::LoopInfo	(	Engine &	,
		const juce::ValueTree &	,
		juce::UndoManager *
	)

Creates a LoopInfo from some existing state.

N.B. this references the given state, it doesn't make a deep copy.

tracktion::engine::LoopInfo::LoopInfo	(	Engine &	,
		const juce::File &
	)

Creates a LoopInfo for an audio file.

◆ LoopInfo() [5/5]

tracktion::engine::LoopInfo::LoopInfo	(	Engine &	,
		const juce::AudioFormatReader *	,
		const juce::AudioFormat *
	)

Creates a LoopInfo for a reader.
