Detailed Description

An AlignableComposite corresponding to a composite GeomDet direct components are AlignableDetUnits or AlignableDets.

Constructor & Destructor Documentation

AlignableDet::AlignableDet	(	const GeomDet *	geomDet,
		bool	addComponents = `true`
	)

Constructor: If addComponents = true, creates components for geomDet's components, assuming they are GeomDetUnits
