Classes
struct	Kaskade::AdaptationCoarseningPolicy
	policy class for LocalTransfer These two structures are used for determining whether to perform a "normal" grid transfer (default, AdaptionCoarseningPolicy), or to calculate prolongation matrices for a FE function space based on a HierarchicIndexSet (see mgtools.hh). More...
struct	Kaskade::MultilevelCoarseningPolicy
	policy class for LocalTransfer These two structures are used for determining whether to perform a "normal" grid transfer (default, AdaptionCoarseningPolicy), or to calculate prolongation matrices for a FE function space based on a HierarchicIndexSet (see mgtools.hh). More...
class	Kaskade::LocalTransfer< Space, CoarseningPolicy >
	Class that stores for a cell ("this entity" or "father") a local projection matrix. More...
class	Kaskade::TransferData< Space, CoarseningPolicy >
	A class storing data collected before grid adaptation that is necessary to transfer FE functions. This includes global indices of shape functions on leaf cells and restriction matrices to coarser cells in case some leaf cells might be removed during grid adaptation. More...
class	Kaskade::TransferData< Space, CoarseningPolicy >::TransferMatrix
	Matrix that transforms a data vector v_1 corresponding to the old grid to a data vector v_2 corresponding to the new grid, such that the functions represented by these vectors coincide as much as possible. More...
struct	Kaskade::InverseVolume
	A Weighing that associates to each cell its inverse volume. More...
struct	Kaskade::Volume
	A Weighing that associates to each cell its volume. More...
struct	Kaskade::PlainAverage
	A Weighing that associates to each cell a constant weight of 1. More...
struct	Kaskade::SumUp< scl >
class	Kaskade::WeakFunctionViewAdaptor< Functor >
	An adaptor that turns callables (e.g., lambdas) into weak function views. More...
class	Kaskade::FunctionViewAdaptor< Space_, Functor >
	An adaptor that allows to turn lambda functions into function views. More...
