virtual	~GmDiscontinuity ()
	Virtuald destructor.
int	index () const
	Returns this discontinuity index in the father set.
QString	id () const
	Returns the discontinuity id (name)
int	cellGroupIndex () const
	Returns the cell group index associated with this discontinuity, if any. This is the index of the group in the list returned by GmCellMesh::cellGroupIds() Returns -1 for an unspecified cell group.
virtual int	propertyIndex (int propertySet) const
	Given a property set number, returns the line of the property set that contains property values for this discontinuity. The returned value can be used to get a property from a property accessor retrieved from the discontinuity set. More...
virtual int	numSegments () const =0
	A generic interface to return the number of discontinuity "segments", where a segment depends on the geometric representation type. For 2d meshes it will be either the number of polyline segments or the number of edges. For 3d meshes, the number of triangles or the number of faces.
virtual int	numIntersections () const =0
	A generic interface to return the number of intersections between the mesh and the user given geometry. Is the number of line segments or faces (triangles an/or quads) in the intersection set.
virtual void	clearGeometry ()=0
	Clears the original discontinuity geometry information, releasing memory.
virtual void	printGeometry (const GmLogCategory &logger, GmLogLevel level) const =0
	Prints the discontinuity geometry information.

Detailed Description

The geometric representation for a single discontinuity from the Discontinuity set. For 2D meshes, it is a polyline. For 3D meshes is a triangulated surface. It can also be represented by edge or face lists.

Member Function Documentation

propertyIndex()

virtual int GmDiscontinuity::propertyIndex ( int  propertySet ) const

inlinevirtual

Given a property set number, returns the line of the property set that contains property values for this discontinuity. The returned value can be used to get a property from a property accessor retrieved from the discontinuity set.

The propertySet number is local to the discontinuity set and varies between 0 and GmDiscontinuitySet::numPropertySets() - 1.

usedGeometryMemory()

virtual size_t GmDiscontinuity::usedGeometryMemory ( ) const

pure virtual

Returns an estimative of the memory used by the discontinuity geometry in bytes.

It returns in general the variable memory that depends on the number of lines in a polyline, edges or faces for boundary lists or points & triangles for surfaces, ignoring "constant" sizes.

Implemented in GmPolylineDiscontinuity, GmTriSurfaceDiscontinuity, GmEdgeListDiscontinuity, and GmFaceListDiscontinuity.
