Detailed Description

template<typename T, typename LFSFlavorTag = AnySpaceTag, typename W = T>
class Dune::PDELab::LocalVector< T, LFSFlavorTag, W >

A container for storing data associated with the degrees of freedom of a LocalFunctionSpace.

This container acts as a wrapper around a std::vector-like container and supports accessing its entries indexed by pairs of (LocalFunctionSpace,DOF of LocalFunctionSpace). If requested by specifying a non-default LFSFlavorTag, the container will also assert that a LocalFunctionSpace of the matching kind (trial or test space) is used to access its content.

Template Parameters

T	The type of values to store in the vector.
LFSFlavorTag	Tag type for differentiating between trial and test space vectors.
W	The type of weight applied in a WeightedAccumulationView.

Member Typedef Documentation

weight_type

template<typename T , typename LFSFlavorTag = AnySpaceTag, typename W = T>

typedef W Dune::PDELab::LocalVector< T, LFSFlavorTag, W >::weight_type

The weight type of this container.

A value of this type will be used to assign a weight to contributions in a WeightedAccumulationView.

Member Function Documentation

operator()() [1/2]

template<typename T , typename LFSFlavorTag = AnySpaceTag, typename W = T>

template<typename LFS >

reference Dune::PDELab::LocalVector< T, LFSFlavorTag, W >::operator() ( const LFS &  lfs, size_type  i  )

inline

Access the value in this container associated with the i-th degree of freedom of the LocalFunctionSpace lfs.

Parameters

lfs	The LocalFunctionSpace for which to retrieve a value. This must be the LFS that has been used to load the values into this vector or one of its children (right now, this is not checked).
i	The index of the degree of freedom of the LocalFunctionSpace that will be returned.

operator()() [2/2]

template<typename T , typename LFSFlavorTag = AnySpaceTag, typename W = T>

template<typename LFS >

const_reference Dune::PDELab::LocalVector< T, LFSFlavorTag, W >::operator() ( const LFS &  lfs, size_type  i  ) const

inline

Access the value in this container associated with the i-th degree of freedom of the LocalFunctionSpace lfs (const version).

Parameters

lfs	The LocalFunctionSpace for which to retrieve a value. This must be the LFS that has been used to load the values into this vector or one of its children (right now, this is not checked).
i	The index of the degree of freedom of the LocalFunctionSpace that will be returned.
