Detailed Description

keep track of edges (defined by pair of integer id's)

vtkGenericEdgeTable is used to indicate the existence of and hold information about edges. Similar to vtkEdgeTable, this class is more sophisticated in that it uses reference counting to keep track of when information about an edge should be deleted.

vtkGenericEdgeTable is a helper class used in the adaptor framework. It is used during the tessellation process to hold information about the error metric on each edge. This avoids recomputing the error metric each time the same edge is visited.

	)

Insert an edge but do not split it.

int vtkGenericEdgeTable::RemoveEdge	(	vtkIdType	e1,
		vtkIdType	e2

Method to remove an edge from the table.

The method returns the current reference count.

int vtkGenericEdgeTable::CheckEdge	(	vtkIdType	e1,
		vtkIdType	e2,
		vtkIdType &	ptId

Method to determine whether an edge is in the table (0 or 1), or not (-1).

It returns whether the edge was split (1) or not (0), and the point id exists.

int vtkGenericEdgeTable::IncrementEdgeReferenceCount	(	vtkIdType	e1,
		vtkIdType	e2,
		vtkIdType	cellId

Method that increments the referencecount and returns it.

int vtkGenericEdgeTable::CheckEdgeReferenceCount	(	vtkIdType	e1,
		vtkIdType	e2
	)

Return the edge reference count.

void vtkGenericEdgeTable::Initialize ( vtkIdType start )

To specify the starting point id.

It will initialize LastPointId This is very sensitive the start point should be cautiously chosen

int vtkGenericEdgeTable::GetNumberOfComponents ( )

Return the total number of components for the point-centered attributes.

Postcondition: positive_result: result>0

void vtkGenericEdgeTable::SetNumberOfComponents ( int count )

Set the total number of components for the point-centered attributes.

Precondition: positive_count: count>0

int vtkGenericEdgeTable::CheckPoint ( vtkIdType ptId )

Check if a point is already in the point table.

int vtkGenericEdgeTable::CheckPoint	(	vtkIdType	ptId,
		double	point[3],
		double *	scalar
	)

Check for the existence of a point and return its coordinate value.

Precondition: scalar_size: sizeof(scalar)==this->GetNumberOfComponents()

void vtkGenericEdgeTable::InsertPoint	(	vtkIdType	ptId,
		double	point[3]
	)

Insert point associated with an edge.

void vtkGenericEdgeTable::InsertPointAndScalar	(	vtkIdType	ptId,
		double	pt[3],
		double *	s
	)

Insert point associated with an edge.

void vtkGenericEdgeTable::RemovePoint ( vtkIdType ptId )

Remove a point from the point table.

void vtkGenericEdgeTable::IncrementPointReferenceCount ( vtkIdType ptId )

Increment the reference count for the indicated point.

void vtkGenericEdgeTable::DumpTable ( )

For debugging purposes.

It is particularly useful to dump the table and check that nothing is left after a complete iteration. LoadFactor should ideally be very low to be able to have a constant time access
