◆ addAlignmentLevel()

void AlignableCompositeBuilder::addAlignmentLevel ( std::unique_ptr< AlignmentLevel > level )

Add all desired AlignmentLevels for a sub-detector to the builder before calling buildAll(), the order matters! Example for PixelBarrel-RunI geometry: -> PXBModule, PXBLadder, TPBLayer, TPBHalfBarrel, TPBBarrel

◆ buildAll()

unsigned int AlignableCompositeBuilder::buildAll	(	AlignableMap &	alignableMap,
		bool	update = `false`
	)

Builds all composite Alignables according to the levels added before via addAlignmentLevel(). The Alignables were built from bottom- to the top- hierarchy, e.g. for PixelBarrel-RunI geometry:

PXBLadder (with PXBModule as children)
TPBLayer (with PXBLadder as children)
TPBHalfBarrel (with TPBLayer as children)
TPBBarrel (with TPBHalfBarrel as children) Returns the number of composite Alignables which were built.
