Detailed Description

template<class Scalar>
class vtkMappedDataArray< Scalar >

Map non-contiguous data structures into the vtkDataArray API.

vtkMappedDataArray is a superclass for vtkDataArrays that do not use the standard memory layout, and allows VTK to interface with simulation codes for in-situ analysis without repacking simulation data.

vtkMappedDataArrayNewInstanceMacro is used by subclasses to implement NewInstanceInternal such that a non-mapped vtkDataArray is returned by NewInstance(). This prevents the mapped array type from propagating through the pipeline.

Attention: Subclasses that hold vtkIdType elements must also reimplement int GetDataType() const (see Caveat in vtkTypedDataArray).

static vtkMappedDataArray< Scalar > * vtkMappedDataArray< Scalar >::FastDownCast ( vtkAbstractArray * source )

static

Perform a fast, safe cast from a vtkAbstractArray to a vtkMappedDataArray.

This method checks if:

source->GetArrayType() is appropriate, and
source->GetDataType() matches the Scalar template argument if these conditions are met, the method performs a static_cast to return source as a vtkMappedDataArray pointer. Otherwise, nullptr is returned.

◆ PrintSelf()

template<class Scalar >

void vtkMappedDataArray< Scalar >::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 vtkDataArray.

◆ DeepCopy() [1/2]

		vtkAbstractArray *	source,
		double *	weights
	)

overridepure virtual

Set the tuple at dstTupleIdx in this array to the interpolated tuple value, given the ptIndices in the source array and associated interpolation weights.

This method assumes that the two arrays are of the same type and structure.

Reimplemented from vtkGenericDataArray< vtkTypedDataArray< Scalar >, Scalar >.

Implemented in vtkCPExodusIINodalCoordinatesTemplate< Scalar >, and vtkCPExodusIIResultsArrayTemplate< Scalar >.

◆ InterpolateTuple() [2/2]

template<class Scalar >

void vtkMappedDataArray< Scalar >::InterpolateTuple	(	vtkIdType	dstTupleIdx,
		vtkIdType	srcTupleIdx1,
		vtkAbstractArray *	source1,

		vtkAbstractArray *	source2,
		double	t
	)

overridepure virtual

Insert the tuple at dstTupleIdx in this array to the tuple interpolated from the two tuple indices, srcTupleIdx1 and srcTupleIdx2, and an interpolation factor, t.

The interpolation factor ranges from (0,1), with t=0 located at the tuple described by srcTupleIdx1. This method assumes that the three arrays are of the same type, srcTupleIdx1 is an index to array source1, and srcTupleIdx2 is an index to array source2.

Reimplemented from vtkGenericDataArray< vtkTypedDataArray< Scalar >, Scalar >.

Implemented in vtkCPExodusIINodalCoordinatesTemplate< Scalar >, and vtkCPExodusIIResultsArrayTemplate< Scalar >.

◆ GetVoidPointer()

template<class Scalar >

void * vtkMappedDataArray< Scalar >::GetVoidPointer ( vtkIdType id )

overridevirtual

Print an error and create an internal, long-lived temporary array.

This method should not be used on vtkMappedDataArray subclasses. See vtkArrayDispatch for a better way.

Reimplemented from vtkGenericDataArray< vtkTypedDataArray< Scalar >, Scalar >.

◆ ExportToVoidPointer()

template<class Scalar >

void vtkMappedDataArray< Scalar >::ExportToVoidPointer ( void * ptr )

overridevirtual

Copy the internal data to the void pointer.

The pointer is cast to this array's Scalar type and vtkTypedDataArrayIterator is used to populate the input array.

Reimplemented from vtkAbstractArray.

◆ DataChanged()

template<class Scalar >

void vtkMappedDataArray< Scalar >::DataChanged ( )

overridevirtual

Read the data from the internal temporary array (created by GetVoidPointer) back into the mapped array.
