Detailed Description

template<typename GFS, typename TAG>
class Dune::PDELab::LocalFunctionSpace< GFS, TAG >

Create a local function space from a global function space.

The local function space can be tagged with one of the tags defined in localfunctionspacetags.hh. This allows to destinguish between trial and test space.

If no TAG is specified the AnySpaceTag is used, which basically states, that it is not clear, whether this is a trial of a test space.

Member Function Documentation

dofIndex()

template<typename GFS , typename DOFIndex >

const Traits::DOFIndex & Dune::PDELab::LocalFunctionSpaceBaseNode< GFS, DOFIndex >::dofIndex ( typename Traits::IndexContainer::size_type  index ) const

inlineinherited

Maps given index in this local function space to its corresponding global MultiIndex.

Parameters

index

The local index value from the range 0,...,size()-1

Returns

A const reference to the associated, globally unique MultiIndex. Note that the returned object may (and must) be copied if it needs to be stored beyond the time of the next call to bind() on this LocalFunctionSpace (e.g. when the MultiIndex is used as a DOF identifier in a constraints container).

localVectorSize()

template<typename GFS , typename DOFIndex >

Traits::IndexContainer::size_type Dune::PDELab::LocalFunctionSpaceBaseNode< GFS, DOFIndex >::localVectorSize ( ) const

inlineinherited

get size of an appropriate local vector object

this is the number of dofs of the complete local function space tree, i.e. the size() of the root node. The local vector objects must always have this size and the localIndex method maps into the range [0,localVectorSize()[
