Public Member Functions
virtual	~GmEdgeListDiscontinuity ()
	Destructor.

template<class T , class V >
static T *	loadIntoVector (LuaTable &tab, V validator, int n, int *realSize, QString discontinuityId, const char *msg, const GmLogCategory &logger)
	Allocate a vector of type T with at most tab.size() * n elements and reads the tab contents into it. Expects that tab is a vector with sub-tables storing n elements. Each loaded element is passed as a variant to the validator function, that should return the converted value to T. The validator should also fill a status variable that says if the value is ok (>=0), ignored (-1) or invalid(-2). Invalid values raise an error and causes loadIntoVector() to log a message and return NULL. Ignored values are simply not added to the result vector (which will be resized accordingly) and are targeted into ignoring cells that don't belong to the current mesh partition. Returns the real size of the vector in the realSize output parameter.
Protected Attributes inherited from GmDiscontinuity
const GmDiscontinuitySet *	_ds
	Our "father" discontinuity set.
int	_index
	The discontinuity index in its "father" discontinuity set.
QString	_id
	The discontinuity id.
int	_groupIndex
	The index in the mesh for the associated cell group or -1 if there is none.
QVector< int >	_psIndex
	The property set line index for this discontinuity. One entry per associated property set.

Member Function Documentation

clearGeometry()

void GmEdgeListDiscontinuity::clearGeometry ( )

virtual

Clears the original discontinuity geometry information, releasing memory.

Implements GmDiscontinuity.

extendGeometry()

virtual bool GmEdgeListDiscontinuity::extendGeometry ( GmCellMesh * sMesh, double size, const GmLogCategory & logger )

inlinevirtual

\breif A generic interface for extending the original geometry by size units. The 'sMesh' is a empty mesh that supports addition of elements and topological consults.

Implements GmDiscontinuity.

loadGeometryFromTable()

bool GmEdgeListDiscontinuity::loadGeometryFromTable ( LuaTable & tab, const GmLogCategory & logger )

privatevirtual

Implements GmDiscontinuity.

numElements()

virtual int GmEdgeListDiscontinuity::numElements ( ) const

inlinevirtual

A generic interface to return the original discontinuity data number of geometric elements. 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.

Implements GmDiscontinuity.

numIntersections()

virtual int GmEdgeListDiscontinuity::numIntersections ( ) const

inlinevirtual

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.

Implements GmDiscontinuity.

numPoints()

virtual int GmEdgeListDiscontinuity::numPoints ( ) const

inlinevirtual

A generic interface to return the original discontinuity data number of points.

Implements GmDiscontinuity.

printGeometry()

void GmEdgeListDiscontinuity::printGeometry ( const GmLogCategory & logger, GmLogLevel level ) const

virtual

Prints the discontinuity geometry information.

Implements GmDiscontinuity.

setGeometry()

virtual void GmEdgeListDiscontinuity::setGeometry ( double * dvec, int nd, int * ivec, int ni )

inlineprivatevirtual

Sets the geometry. ivec should be a vector with cell id + edge id pairs (size ni * 2), ni the number of edges. dvec should be NULL.

Implements GmDiscontinuity.

usedGeometryMemory()

virtual size_t GmEdgeListDiscontinuity::usedGeometryMemory ( ) const

inlinevirtual

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.

Implements GmDiscontinuity.
