Detailed Description

template<class T>
class CoDimCopyManager< T >

Helper class to manage CoDim exchange operations.

CoDimCopiers are designed to be exercised in order, starting with CoDim=2 and increasing to SpaceDim. The CoDimCopyManager class manages these operations.

◆ CoDimCopyManager() [2/2]

template<class T >

CoDimCopyManager< T >::CoDimCopyManager	(	const DisjointBoxLayout &	a_grids,
		const BoxLayout &	a_dest,
		const IntVect &	a_ghostVect,
		bool	a_exchange = `false`,
		int	a_maxCoDim = `SpaceDim`
	)

defining constructor – calls matching define function

by default, does all coDim copies from CoDim=2->SpaceDim. If you know you only need coDim ghost cells up to a Co-dimension less than SpaceDim, that can be specified, which will make things cheaper.
