Detailed Description

abstract superclass for arrays of numeric data

vtkDataArray is an abstract superclass for data array objects containing numeric data. It extends the API defined in vtkAbstractArray. vtkDataArray is an abstract superclass for data array objects. This class defines an API that all array objects must support. Note that the concrete subclasses of this class represent data in native form (char, int, etc.) and often have specialized more efficient methods for operating on this data (for example, getting pointers to data or getting/inserting data in native form). Subclasses of vtkDataArray are assumed to contain data whose components are meaningful when cast to and from double.

	)			`[virtual]`

Insert the ith tuple in this array as interpolated from the two values, p1 and p2, and an interpolation factor, t. The interpolation factor ranges from (0,1), with t=0 located at p1. This method assumes that the three arrays are of the same type. p1 is value at index id1 in source1, while, p2 is value at index id2 in source2.

Implements vtkAbstractArray.

virtual double* vtkDataArray::GetTuple ( vtkIdType i ) [pure virtual]

Return the range of the array values for the given component. Range is copied into the array provided. If comp is equal to -1, it returns the range of the magnitude (if the number of components is equal to 1 it still returns the range of component 0).

static void vtkDataArray::GetDataTypeRange	(	int	type,
		double	range[2]
	)			`[static]`

Return the range of the array values for the given component. Range is copied into the array provided. If comp is equal to -1, it returns the range of the magnitude (if the number of components is equal to 1 it still returns the range of component 0).

static double vtkDataArray::GetDataTypeMin ( int type ) [static]

Return the range of the array values for the given component. Range is copied into the array provided. If comp is equal to -1, it returns the range of the magnitude (if the number of components is equal to 1 it still returns the range of component 0).

static double vtkDataArray::GetDataTypeMax ( int type ) [static]

Return the range of the array values for the given component. Range is copied into the array provided. If comp is equal to -1, it returns the range of the magnitude (if the number of components is equal to 1 it still returns the range of component 0).

static vtkInformationInformationVectorKey* vtkDataArray::PER_COMPONENT ( ) [static]

This key is used to hold a vector of COMPONENT_RANGE keys -- one for each component of the array. You may add additional per-component key-value pairs to information objects in this vector. However if you do so, you must be sure to either (1) set COMPONENT_RANGE to { VTK_DOUBLE_MAX, VTK_DOUBLE_MIN } or (2) call ComputeRange( component ) before modifying the information object. Otherwise it is possible for modifications to the array to take place without the bounds on the component being updated since the modification time of the vtkInformation object is used to determine when the COMPONENT_RANGE values are out of date.

static vtkInformationDoubleVectorKey* vtkDataArray::COMPONENT_RANGE ( ) [static]

This key is used to hold a vector of COMPONENT_RANGE keys -- one for each component of the array. You may add additional per-component key-value pairs to information objects in this vector. However if you do so, you must be sure to either (1) set COMPONENT_RANGE to { VTK_DOUBLE_MAX, VTK_DOUBLE_MIN } or (2) call ComputeRange( component ) before modifying the information object. Otherwise it is possible for modifications to the array to take place without the bounds on the component being updated since the modification time of the vtkInformation object is used to determine when the COMPONENT_RANGE values are out of date.

static vtkInformationDoubleVectorKey* vtkDataArray::L2_NORM_RANGE ( ) [static]

virtual int vtkDataArray::CopyInformation	(	vtkInformation *	infoFrom,
		int	deep = `1`
	)			`[virtual]`

Copy information instance. Arrays use information objects in a variety of ways. It is important to have flexibility in this regard because certain keys should not be coppied, while others must be. NOTE: Up to the implmeneter to make sure that keys not inteneded to be coppied are excluded here.

Reimplemented from vtkAbstractArray.

virtual void vtkDataArray::ComputeRange ( int comp ) [protected, virtual]

Compute the range for a specific component. If comp is set -1 then L2 norm is computed on all components. Call ClearRange to force a recomputation if it is needed.

virtual void vtkDataArray::ComputeScalarRange ( int comp ) [protected, virtual]

Compute the range for a specific component. If comp is set -1 then L2 norm is computed on all components. Call ClearRange to force a recomputation if it is needed.

Reimplemented in vtkDataArrayTemplate< T >.

virtual void vtkDataArray::ComputeVectorRange ( ) [protected, virtual]

Compute the range for a specific component. If comp is set -1 then L2 norm is computed on all components. Call ClearRange to force a recomputation if it is needed.
