DMComplexSetConeOrientation

Set the orientations on the in-edges for this point in the Sieve DAG

#include "petscdmcomplex.h"   
PetscErrorCode DMComplexSetConeOrientation(DM dm, PetscInt p, const PetscInt coneOrientation[])

Not collective

	mesh	- The DMComplex
	p	- The Sieve point, which must lie in the chart set with DMComplexSetChart()
	coneOrientation	- An array of orientations which are on the in-edges for point p. An orientation is an integer giving the prescription for cone traversal. If it is negative, the cone is traversed in the opposite direction. Its value 'o', or if negative '-(o+1)', gives the index of the cone point on which to start.

This should be called after all calls to DMComplexSetConeSize() and DMSetUp().
