Detailed Description

A simple grid class for triangulations.

This class may act as a wrapper with reference-semantics for a plain array containing the cell-vertex connectivity. Value semantics may be enforced by a call to the member function DoCopy().

A copy by assignment or copy-ctor will always entail value-semantics on the copied-to side, i.e. make a full copy.

As this class also serves as a tutorial on how to adapt existing data structures to GrAL, the technical level was kept low, i.e. there are no complicated constructions for building element and iterators types out of generic components.

Member Function Documentation

Triang2D & Triang2D::operator= (  Triang2D const &    rhs )

Definition at line 15 of file triang2d.C. References cells, ncells, and nvertices.

void Triang2D::DoCopy (    )

make a physical copy, if only referencing the grid, thus gaining ownership of cells. Definition at line 70 of file triang2d.C.

void Triang2D::Steal (  int *    c, int    nc, int    nv )

set this to the connectivity given by c. Assume ownership of c *without* doing a copy. Definition at line 72 of file triang2d.C. Referenced by copy_cells.
