Detailed Description

extracts a selection over time.

vtkExtractArraysOverTime extracts a selection over time. The output is a multiblock dataset. If selection content type is vtkSelection::Locations, then each output block corresponds to each probed location. Otherwise, each output block corresponds to an extracted cell/point depending on whether the selection field type is CELL or POINT. Each block is a vtkTable with a column named Time (or TimeData if Time exists in the input). When extracting point data, the input point coordinates are copied to a column named Point Coordinates or Points (if Point Coordinates exists in the input). This algorithm does not produce a TIME_STEPS or TIME_RANGE information because it works across time.

Caveat:: This algorithm works only with source that produce TIME_STEPS(). Continuous time range is not yet supported.

Member Function Documentation

static vtkExtractArraysOverTime* vtkExtractArraysOverTime::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkMultiBlockDataSetAlgorithm.

Reimplemented in vtkPExtractArraysOverTime.

static int vtkExtractArraysOverTime::IsTypeOf ( const char * name ) [static]

Return 1 if this class type 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 vtkMultiBlockDataSetAlgorithm.

Reimplemented in vtkPExtractArraysOverTime.

virtual int vtkExtractArraysOverTime::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 vtkMultiBlockDataSetAlgorithm.

Reimplemented in vtkPExtractArraysOverTime.

static vtkExtractArraysOverTime* vtkExtractArraysOverTime::SafeDownCast ( vtkObjectBase * o ) [static]

void vtkExtractArraysOverTime::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)		`[virtual]`

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 vtkMultiBlockDataSetAlgorithm.

Reimplemented in vtkPExtractArraysOverTime.

virtual int vtkExtractArraysOverTime::GetNumberOfTimeSteps ( ) [virtual]

Get the number of time steps

void vtkExtractArraysOverTime::SetSelectionConnection ( vtkAlgorithmOutput * algOutput ) [inline]

Convenience method to specify the selection connection (2nd input port)

Definition at line 62 of file vtkExtractArraysOverTime.h.

virtual void vtkExtractArraysOverTime::SetSelectionExtractor ( vtkExtractSelection * ) [virtual]

Set/get the vtkExtractSelection instance used to obtain array values at each time step. An instance of vtkExtractSelection is created on demand when the filter is first executed. This is used by ParaView to override the default extractor with one that supports Python-based QUERY selection.

virtual vtkExtractSelection* vtkExtractArraysOverTime::GetSelectionExtractor ( ) [virtual]

Set/get the vtkExtractSelection instance used to obtain array values at each time step. An instance of vtkExtractSelection is created on demand when the filter is first executed. This is used by ParaView to override the default extractor with one that supports Python-based QUERY selection.

virtual void vtkExtractArraysOverTime::SetReportStatisticsOnly ( int ) [virtual]

Instead of breaking a selection into a separate time-history table for each (block,ID)-tuple, you may call ReportStatisticsOnlyOn(). Then a single table per block of the input dataset will report the minimum, maximum, quartiles, and (for numerical arrays) the average and standard deviation of the selection over time. The default is off to preserve backwards-compatibility.

virtual int vtkExtractArraysOverTime::GetReportStatisticsOnly ( ) [virtual]

Instead of breaking a selection into a separate time-history table for each (block,ID)-tuple, you may call ReportStatisticsOnlyOn(). Then a single table per block of the input dataset will report the minimum, maximum, quartiles, and (for numerical arrays) the average and standard deviation of the selection over time. The default is off to preserve backwards-compatibility.

virtual void vtkExtractArraysOverTime::ReportStatisticsOnlyOn ( ) [virtual]

Then a single table per block of the input dataset will report the minimum, maximum, quartiles, and (for numerical arrays) the average and standard deviation of the selection over time.

virtual void vtkExtractArraysOverTime::ReportStatisticsOnlyOff ( ) [virtual]

Instead of breaking a selection into a separate time-history table for each (block,ID)-tuple, you may call ReportStatisticsOnlyOn(). Then a single table per block of the input dataset will report the minimum, maximum, quartiles, and (for numerical arrays) the average and standard deviation of the selection over time.

virtual int vtkExtractArraysOverTime::RequestInformation	(	vtkInformation *	,

This is called by the superclass. This is the method you should override.

		vtkInformationVector **	,
		vtkInformationVector *
	)		`[protected, virtual]`

This is called by the superclass. This is the method you should override.

		vtkInformationVector *	outputVector
	)		`[protected, virtual]`

Reimplemented in vtkPExtractArraysOverTime.

int vtkExtractArraysOverTime::DetermineSelectionType ( vtkSelection * ) [protected]

Determines the FieldType and ContentType for the selection. If the selection is a vtkSelection::SELECTIONS selection, then this method ensures that all child nodes have the same field type and content type otherwise, it returns 0.

virtual int vtkExtractArraysOverTime::FillInputPortInformation	(	int	port,
		vtkInformation *	info
	)		`[protected, virtual]`

Fill the input port information objects for this algorithm. This is invoked by the first call to GetInputPortInformation for each port so subclasses can specify what they can handle.
