Member Function Documentation

◆ IsTypeOf()

static vtkTypeBool vtkDIYUtilities::IsTypeOf ( const char * type )

static

◆ IsA()

virtual vtkTypeBool vtkDIYUtilities::IsA ( const char * name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObjectBase.

◆ SafeDownCast()

static vtkDIYUtilities * vtkDIYUtilities::SafeDownCast ( vtkObjectBase * o )

static

◆ NewInstanceInternal()

virtual vtkObjectBase * vtkDIYUtilities::NewInstanceInternal ( ) const

protectedvirtual

◆ NewInstance()

vtkDIYUtilities * vtkDIYUtilities::NewInstance ( ) const

◆ PrintSelf()

void vtkDIYUtilities::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObject.

◆ InitializeEnvironmentForDIY()

static void vtkDIYUtilities::InitializeEnvironmentForDIY ( )

static

In MPI-enabled builds, DIY filters need MPI to be initialized.

Calling this method in such filters will ensure that that's the case.

◆ GetCommunicator()

static diy::mpi::communicator vtkDIYUtilities::GetCommunicator ( vtkMultiProcessController * controller )

static

Converts a vtkMultiProcessController to a diy::mpi::communicator.

If controller is nullptr or not a vtkMPIController, then diy::mpi::communicator(MPI_COMM_NULL) is created.

◆ Save() [1/4]

static void vtkDIYUtilities::Save	(	diy::BinaryBuffer &	bb,
		vtkDataSet *
	)

static

Load/Save a vtkDataSet in a diy::BinaryBuffer.

◆ Load() [1/4]

◆ Save() [2/4]

static void vtkDIYUtilities::Save	(	diy::BinaryBuffer &	bb,
		vtkFieldData *
	)

static

Load/Save a vtkFieldData in a diy::BinaryBuffer.

◆ Load() [2/4]

static void vtkDIYUtilities::Load	(	diy::BinaryBuffer &	bb,
		vtkFieldData *&
	)

static

Load/Save a vtkFieldData in a diy::BinaryBuffer.

◆ Save() [3/4]

static void vtkDIYUtilities::Save	(	diy::BinaryBuffer &	bb,
		vtkStringArray *
	)

static

◆ Save() [4/4]

static void vtkDIYUtilities::Save	(	diy::BinaryBuffer &	bb,
		vtkDataArray *
	)

static

Load/Save a vtkDataArray in a diy::BinaryBuffer.

◆ Load() [4/4]

static void vtkDIYUtilities::Load	(	diy::BinaryBuffer &	bb,
		vtkDataArray *&
	)

static

Load/Save a vtkDataArray in a diy::BinaryBuffer.

◆ AllReduce()

static void vtkDIYUtilities::AllReduce	(	diy::mpi::communicator &	comm,
		vtkBoundingBox &	bbox
	)

static

Reduce bounding box.

◆ Convert() [1/2]

static diy::ContinuousBounds vtkDIYUtilities::Convert ( const vtkBoundingBox & bbox )

static

Convert vtkBoundingBox to diy::ContinuousBounds.

Note, there is a loss of precision since vtkBoundingBox uses double while diy::ContinuousBounds uses float.

◆ Convert() [2/2]

static vtkBoundingBox vtkDIYUtilities::Convert ( const diy::ContinuousBounds & bds )

static

Convert diy::ContinuousBounds to vtkBoundingBox.

Note, there is a change of precision since vtkBoundingBox uses double while diy::ContinuousBounds uses float.

◆ Broadcast()

static void vtkDIYUtilities::Broadcast	(	diy::mpi::communicator &	comm,
		std::vector< vtkBoundingBox > &	boxes,
		int	source
	)

static

Broadcast a vector of bounding boxes.

Only the source vector needs to have a valid size.

◆ GetDataSets()

template<class DataSetT = vtkDataSet>

static std::vector< DataSetT * > vtkDIYUtilities::GetDataSets ( vtkDataObject * dobj )

static

Extract datasets from the given data object.

This method returns a vector of DataSetT* from the dobj. If dobj is a DataSetT, the returned vector will have just 1 DataSetT. If dobj is a vtkCompositeDataSet, then we iterate over it and add all non-null leaf nodes to the returned vector.

◆ ExtractPoints()

static std::vector< vtkSmartPointer< vtkPoints > > vtkDIYUtilities::ExtractPoints	(	const std::vector< vtkDataSet * > &	datasets,
		bool	use_cell_centers
	)

static

Extracts points from the input.

If input is not a vtkPointSet, it will use an appropriate filter to extract the vtkPoints. If use_cell_centers is true, cell-centers will be computed and extracted instead of the dataset points.

◆ GetLocalBounds()

static vtkBoundingBox vtkDIYUtilities::GetLocalBounds ( vtkDataObject * dobj )

static

Convenience method to get local bounds for the data object.

◆ Link() [1/2]

template<class DummyT >

static void vtkDIYUtilities::Link	(	diy::Master &	master,
		const diy::Assigner &	assigner,
		const std::vector< std::map< int, DummyT > > &	linksMap
	)

static

Links master such that there is communication between ranks as given in linksMap.

linksMap is a vector of a list of global ids. The size of this vector should be the same as the number of blocks in the current rank and should map to the block of same local id. The associated list of global ids will tell which block is to be connected with the local block.

◆ Link() [2/2]

static void vtkDIYUtilities::Link	(	diy::Master &	master,
		const diy::Assigner &	assigner,
		const std::vector< std::set< int > > &	linksMap
	)

static
