Detailed Description

Class allows to iterate over sides of neighbour.

Class returns only local cells (owns + ghosts), non-local cells are skipped.

Iterator is defined by:

• DOF handler cell accessor
• index of Neighbour on cell (iterated value)
• maximal index of Neighbour (allow to skip non-local cells)

Note: Class is used only internally. Appropriate range method (DHCellAccessor::neighb_sides) uses convertible iterators and returns corresponding DHCellSide.

Constructor & Destructor Documentation

DHNeighbSide::DHNeighbSide ( )

inline

Default invalid accessor.

Definition at line 332 of file dh_cell_accessor.hh.

DHNeighbSide::DHNeighbSide ( const DHCellAccessor &  dh_cell, unsigned int  neighb_idx, unsigned int  max_idx  )

inline

Valid accessor allows iterate over neighbor sides.

Parameters

dh_cell	Element of lower dim.
neighb_idx	Index of neighbour.
max_idx	Maximal index of neighbour, method inc() doesn't set neighb_idx_ on higher value.

Definition at line 341 of file dh_cell_accessor.hh.
