Detailed Description

template<class Size, class ContainerIndex_, MultiIndexOrder OriginOrder>
struct Dune::PDELab::SizeProviderAdapter< Size, ContainerIndex_, OriginOrder >

Adapter to create a size provider from an ordering.

This adapter is meant to be used in allocation and resizing of vectors containers. In particular, this adapter is needed because the ordering library give sizes for multi-indices ordered with Inner2Outer semantis, while resizing algorithms are faster and easier when using Outer2Inner semantics.

  • This class makes type erasure on the ordering type.
  • This class has value semantics.
  • This class always receives container indices with Outer2Inner order
Template Parameters
SizeType_return type of the size method
ContainerIndex_argument type of the size method
OriginOrderenum with MultiIndexOrder semantics of the origin ordering
