Detailed Description

A superclass for reading netCDF files.

Subclass add conventions to the reader. This class just outputs data into a multi block data set with a vtkImageData at each block. A block is created for each variable except that variables with matching dimensions will be placed in the same block.

static

◆ IsA()

virtual vtkTypeBool vtkNetCDFReader::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.

◆ PrintSelf()

void vtkNetCDFReader::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 vtkDataObjectAlgorithm.

◆ SetFileName()

virtual void vtkNetCDFReader::SetFileName ( VTK_FILEPATH const char * filename )

virtual

◆ vtkGetFilePathMacro()

vtkNetCDFReader::vtkGetFilePathMacro ( FileName )

◆ UpdateMetaData()

int vtkNetCDFReader::UpdateMetaData ( )

Update the meta data from the current file.

Automatically called during the RequestInformation pipeline update stage.

◆ GetNumberOfVariableArrays()

virtual int vtkNetCDFReader::GetNumberOfVariableArrays ( )

virtual

Variable array selection.

◆ GetVariableArrayName()

virtual const char * vtkNetCDFReader::GetVariableArrayName ( int index )

virtual

Variable array selection.

◆ GetVariableArrayStatus()

virtual int vtkNetCDFReader::GetVariableArrayStatus ( const char * name )

virtual

Variable array selection.

◆ SetVariableArrayStatus()

virtual void vtkNetCDFReader::SetVariableArrayStatus	(	const char *	name,
		int	status
	)

virtual

Variable array selection.

◆ GetAllVariableArrayNames()

virtual vtkStringArray * vtkNetCDFReader::GetAllVariableArrayNames ( )

virtual

Convenience method to get a list of variable arrays.

The length of the returned list is the same as GetNumberOfVariableArrays, and the string at each index i is the same as returned from GetVariableArrayname(i).

◆ GetVariableDimensions()

virtual vtkStringArray * vtkNetCDFReader::GetVariableDimensions ( )

virtual

Returns an array with string encodings for the dimensions used in each of the variables.

The indices in the returned array correspond to those used in the GetVariableArrayName method. Two arrays with the same dimensions will have the same encoded string returned by this method.

◆ SetDimensions()

virtual void vtkNetCDFReader::SetDimensions ( const char * dimensions )

virtual

Loads the grid with the given dimensions.

The dimensions are encoded in a string that conforms to the same format as returned by GetVariableDimensions and GetAllDimensions. This method is really a convenience method for SetVariableArrayStatus. It turns on all variables that have the given dimensions and turns off all other variables.

◆ ComputeArraySelection()

bool vtkNetCDFReader::ComputeArraySelection ( )

Enables arrays in VariableArraySelection depending on Dimensions.

Returns true if one variable matching Dimensions was found.

◆ GetAllDimensions()

virtual vtkStringArray * vtkNetCDFReader::GetAllDimensions ( )

virtual

Returns an array with string encodings for the dimension combinations used in the variables.

The result is the same as GetVariableDimensions except that each entry in the array is unique (a set of dimensions is only given once even if it occurs for multiple variables) and the order is meaningless.

◆ GetReplaceFillValueWithNan()

virtual vtkTypeBool vtkNetCDFReader::GetReplaceFillValueWithNan ( )

virtual

If on, any float or double variable read that has a _FillValue attribute will have that fill value replaced with a not-a-number (NaN) value.

The advantage of setting these to NaN values is that, if implemented properly by the system and careful math operations are used, they can implicitly be ignored by calculations like finding the range of the values. That said, this option should be used with caution as VTK does not fully support NaN values and therefore odd calculations may occur. By default this is off.

◆ SetReplaceFillValueWithNan()

virtual void vtkNetCDFReader::SetReplaceFillValueWithNan ( vtkTypeBool )

virtual

If on, any float or double variable read that has a _FillValue attribute will have that fill value replaced with a not-a-number (NaN) value.

The advantage of setting these to NaN values is that, if implemented properly by the system and careful math operations are used, they can implicitly be ignored by calculations like finding the range of the values. That said, this option should be used with caution as VTK does not fully support NaN values and therefore odd calculations may occur. By default this is off.

◆ ReplaceFillValueWithNanOn()

virtual void vtkNetCDFReader::ReplaceFillValueWithNanOn ( )

virtual

If on, any float or double variable read that has a _FillValue attribute will have that fill value replaced with a not-a-number (NaN) value.

The advantage of setting these to NaN values is that, if implemented properly by the system and careful math operations are used, they can implicitly be ignored by calculations like finding the range of the values. That said, this option should be used with caution as VTK does not fully support NaN values and therefore odd calculations may occur. By default this is off.

◆ ReplaceFillValueWithNanOff()

virtual void vtkNetCDFReader::ReplaceFillValueWithNanOff ( )

virtual

If on, any float or double variable read that has a _FillValue attribute will have that fill value replaced with a not-a-number (NaN) value.

The advantage of setting these to NaN values is that, if implemented properly by the system and careful math operations are used, they can implicitly be ignored by calculations like finding the range of the values. That said, this option should be used with caution as VTK does not fully support NaN values and therefore odd calculations may occur. By default this is off.

◆ GetTimeUnits()

virtual char * vtkNetCDFReader::GetTimeUnits ( )

virtual

Access to the time dimensions units.

Can be used by the udunits library to convert raw numerical time values into meaningful representations.

◆ GetCalendar()

virtual char * vtkNetCDFReader::GetCalendar ( )

virtual

Access to the time dimensions units.

Can be used by the udunits library to convert raw numerical time values into meaningful representations.

◆ QueryArrayUnits()

std::string vtkNetCDFReader::QueryArrayUnits ( const char * ArrayName )

Get units attached to a particular array in the netcdf file.

◆ RequestDataObject()

int vtkNetCDFReader::RequestDataObject	(	vtkInformation *	,
		vtkInformationVector **	,
		vtkInformationVector *
	)

overrideprotectedvirtual

This is called by the superclass.

This is the method you should override.

Reimplemented from vtkDataObjectAlgorithm.

◆ RequestInformation()

int vtkNetCDFReader::RequestInformation	(	vtkInformation *	request,
		vtkInformationVector **	inputVector,
		vtkInformationVector *	outputVector
	)

overrideprotectedvirtual

Reimplemented from vtkDataObjectAlgorithm.

◆ RequestData()

int vtkNetCDFReader::RequestData	(	vtkInformation *	request,
		vtkInformationVector **	inputVector,
		vtkInformationVector *	outputVector
	)

overrideprotectedvirtual

Reimplemented from vtkDataObjectAlgorithm.

◆ SelectionModifiedCallback()

static void vtkNetCDFReader::SelectionModifiedCallback	(	vtkObject *	caller,
		unsigned long	eid,
		void *	clientdata,
		void *	calldata
	)

staticprotected

Callback registered with the VariableArraySelection.

◆ DescribeDimensions()

vtkStdString vtkNetCDFReader::DescribeDimensions	(	int	ncFD,
		const int *	dimIds,
		int	numDims
	)

protected

Convenience function for getting a string that describes a set of dimensions.

◆ ReadMetaData()

virtual int vtkNetCDFReader::ReadMetaData ( int ncFD )

protectedvirtual

Reads meta data and populates ivars.

Returns 1 on success, 0 on failure.

Reimplemented in vtkNetCDFCFReader.

◆ FillVariableDimensions()

virtual int vtkNetCDFReader::FillVariableDimensions ( int ncFD )

protectedvirtual

Fills the VariableDimensions array.

◆ IsTimeDimension()

virtual int vtkNetCDFReader::IsTimeDimension	(	int	ncFD,
		int	dimId
	)

protectedvirtual

Determines whether the given variable is a time dimension.

The default implementation bases the decision on the name of the variable. Subclasses should override this function if there is a more specific way to identify the time variable. This method is always called after ReadMetaData for a given file.

Reimplemented in vtkNetCDFCFReader.

◆ GetTimeValues()

virtual vtkSmartPointer< vtkDoubleArray > vtkNetCDFReader::GetTimeValues	(	int	ncFD,
		int	dimId
	)

protectedvirtual

Given a dimension already determined to be a time dimension (via a call to IsTimeDimension) returns an array with time values.

The default implementation just uses the time index for the time value. Subclasses should override this function if there is a convention that identifies time values. This method returns 0 on error, 1 otherwise.

Reimplemented in vtkNetCDFCFReader.

◆ DimensionsAreForPointData()

virtual bool vtkNetCDFReader::DimensionsAreForPointData ( vtkIntArray * vtkNotUseddimensions )

inlineprotectedvirtual

Called internally to determine whether a variable with the given set of dimensions should be loaded as point data (return true) or cell data (return false).

The implementation in this class always returns true. Subclasses should override to load cell data for some or all variables.

Definition at line 243 of file vtkNetCDFReader.h.

◆ GetUpdateExtentForOutput()

virtual void vtkNetCDFReader::GetUpdateExtentForOutput	(	vtkDataSet *	output,
		int	extent[6]
	)

protectedvirtual

Retrieves the update extent for the output object.

The default implementation just gets the update extent from the object as you would expect. However, if a subclass is loading an unstructured data set, this gives it a chance to set the range of values to read.

Reimplemented in vtkNetCDFCFReader.

◆ LoadVariable()

virtual int vtkNetCDFReader::LoadVariable	(	int	ncFD,
		const char *	varName,
		double	time,
		vtkDataSet *	output
	)

protectedvirtual

Load the variable at the given time into the given data set.

Return 1 on success and 0 on failure.
