inlineinherited

Marks an entity to be refined/coarsened in a subsequent adapt.

Parameters

[in]	refCount	Number of subdivisions that should be applied. Negative value means coarsening.
[in]	e	Entity that should be marked

Returns: true if Entity was marked, false otherwise.

◆ mark() [2/3]

bool Dune::GridDefaultImplementation< dim, dimworld, HostGrid::ctype , IdentityGridFamily< HostGrid::dimension, HostGrid > >::mark	(	int	refCount,

inlineinherited

Marks an entity to be refined/coarsened in a subsequent adapt.

Parameters

[in]	refCount	Number of subdivisions that should be applied. Negative value means coarsening.
[in]	e	Entity to Entity that should be refined

Returns: true if Entity was marked, false otherwise.

Note

default implementation is: return false; for grids with no adaptation.
for the grid programmer: this method is implemented as a template method, because the Entity type is not defined when the class is instantiated You won't need this trick in the implementation. In your implementation you should use it as
bool mark( int refCount,

typename Traits::template Codim<0>::Entity & e ).

Dune::Grid::Codim
A Traits struct that collects all associated types of one implementation.
Definition common/grid.hh:411

Dune::GridTraits::Codim
Traits associated with a specific codim.
Definition common/grid.hh:1035

Dune::IdentityGrid::mark
bool mark(int refCount, const typename Traits::template Codim< 0 >::Entity &e)
Mark entity for refinement.
Definition identitygrid.hh:318

This template method will vanish due to the inheritance rules.
