Detailed Description

template<typename GV, typename P>
class Dune::PDELab::PartitionViewEntitySet< GV, P >

Partition view (or entity set) of a grid view.

The partition view creates an index set for the given partition which allows to exclude unused codimensions. Additionally, it allows to retreive a unique index for every entity contained in the index set (Similar to the MCMG mapper functionality). This is particularly useful when working with Local Finite Elements that do not attach DOFs to all codimensions.

Note

A copy of this class is a shallow copy on the underlying index set

Template Parameters

GV	Grid view
P	PartitionSet to restrict view of the entity set

Member Function Documentation

operator==()

template<typename GV , typename P >

bool Dune::PDELab::PartitionViewEntitySet< GV, P >::operator== ( const PartitionViewEntitySet< GV, P > &  other ) const

inline

Compare to another partition view.

This check only succeeds for copies of this class

Parameters

other

Another partition view

Returns

true if other shares the same index set as this

false otherwise

update()

template<typename GV , typename P >

bool Dune::PDELab::PartitionViewEntitySet< GV, P >::update ( bool  force = false )

inline

Update the internal state of this EntitySet.

Parameters

force

If true, forces an update even if the EntitySet parameters have not changed. This is e.g. required if the underlying grid has changed due to adaptivity.

Returns

Returns true if the state of the EntitySet was changed by this method.
