Detailed Description

Helper class to process file series.

vtkFileSeriesHelper is intended to be a helper class that processes file series. File series encountered in ParaView are of two types: temporal or spatial. This class encapsulates logic to determine which form it is in.

Currently, this is used by vtkCGNSFileSeriesReader. Eventually, we should be able to refactor vtkFileSeriesReader to use this class.

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.

◆ PrintSelf()

void vtkFileSeriesHelper::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.

◆ RemoveAllFileNames()

void vtkFileSeriesHelper::RemoveAllFileNames ( )

Specify the set of files that comprise the series.

◆ AddFileName()

void vtkFileSeriesHelper::AddFileName ( const char * fname )

Specify the set of files that comprise the series.

◆ SetFileNames()

void vtkFileSeriesHelper::SetFileNames ( const std::vector< std::string > & filenames )

Specify the set of files that comprise the series.

◆ GetNumberOfFiles()

unsigned int vtkFileSeriesHelper::GetNumberOfFiles ( ) const

Get the number of files in the series.

◆ ReadMetaFile()

virtual bool vtkFileSeriesHelper::ReadMetaFile ( const char * metafilename )

virtual

Setup file names in the series using a meta-file.

The meta-file is simply lists the names of the files in the series sequentially in an ASCII file. All files in the file are relative to the location of the meta-file or absolute paths.

This will remove an preexisting files added to the helper irrespective of whether reading of the meta-file succeeded or not.

Returns: false if failed to read the meta-file, true otherwise.

◆ SetController()

void vtkFileSeriesHelper::SetController ( vtkMultiProcessController * )

Get/Set the parallel controller.

By default vtkMultiProcessController::GetGlobalController() will be used.

◆ GetController()

virtual vtkMultiProcessController * vtkFileSeriesHelper::GetController ( )

virtual

Get/Set the parallel controller.

By default vtkMultiProcessController::GetGlobalController() will be used.

◆ SetIgnoreReaderTime()

virtual void vtkFileSeriesHelper::SetIgnoreReaderTime ( bool )

virtual

In vtkFileSeriesHelper::UpdateInformation, vtkFileSeriesHelper tries to determine time information from the reader by making it read each of the files and then collecting the timesteps provided by each.

Sometimes, however, the time steps in the files in the fileseries are invalid (or same) in which case one may want to to simply use the time-step index as the time value. For that case, one should set IgnoreReaderTime to true (default: false).

◆ GetIgnoreReaderTime()

virtual bool vtkFileSeriesHelper::GetIgnoreReaderTime ( )

virtual

In vtkFileSeriesHelper::UpdateInformation, vtkFileSeriesHelper tries to determine time information from the reader by making it read each of the files and then collecting the timesteps provided by each.

Sometimes, however, the time steps in the files in the fileseries are invalid (or same) in which case one may want to to simply use the time-step index as the time value. For that case, one should set IgnoreReaderTime to true (default: false).

◆ IgnoreReaderTimeOn()

virtual void vtkFileSeriesHelper::IgnoreReaderTimeOn ( )

virtual

In vtkFileSeriesHelper::UpdateInformation, vtkFileSeriesHelper tries to determine time information from the reader by making it read each of the files and then collecting the timesteps provided by each.

Sometimes, however, the time steps in the files in the fileseries are invalid (or same) in which case one may want to to simply use the time-step index as the time value. For that case, one should set IgnoreReaderTime to true (default: false).

◆ IgnoreReaderTimeOff()

virtual void vtkFileSeriesHelper::IgnoreReaderTimeOff ( )

virtual

In vtkFileSeriesHelper::UpdateInformation, vtkFileSeriesHelper tries to determine time information from the reader by making it read each of the files and then collecting the timesteps provided by each.

Sometimes, however, the time steps in the files in the fileseries are invalid (or same) in which case one may want to to simply use the time-step index as the time value. For that case, one should set IgnoreReaderTime to true (default: false).

◆ UpdateInformation()

virtual bool vtkFileSeriesHelper::UpdateInformation	(	vtkAlgorithm *	reader,
		const FileNameFunctorType &	ftor
	)

virtual

vtkFileSeriesHelper needs to collect information about the nature of the fileseries.

This method should be called to collect this information.

This method has any effect only when the filenames (or any ivar that could affect the times e.g. IgnoreReaderTime) have changed, hence calling this repeatedly is acceptable.

When this method does any work, it updates this->UpdateInformationTime. One can use GetUpdateInformationTime to check if the file series has potentially been changed.

Parameters

[in]	reader	pointer to the single file reader to use.
[in]	ftor	callback to set the filename on the reader.

Returns: false if no filenames are specified or failed to collect meta-data.

◆ GetUpdateInformationTime()

virtual vtkMTimeType vtkFileSeriesHelper::GetUpdateInformationTime ( )

virtual

The time stamp for the most recent UpdateInformation call that did some work to update the file series.

◆ GetTimeSteps()

const std::vector< double > & vtkFileSeriesHelper::GetTimeSteps ( ) const

inline

Returns the timesteps determined.

This method will return valid values only after a successful call to UpdateInformation.

Definition at line 132 of file vtkFileSeriesHelper.h.

◆ GetTimeRange()

const std::pair< double, double > & vtkFileSeriesHelper::GetTimeRange ( bool * isvalid = NULL ) const

inline

Returns the time range determined.

Definition at line 137 of file vtkFileSeriesHelper.h.

◆ FillTimeInformation()

void vtkFileSeriesHelper::FillTimeInformation ( vtkInformation * info ) const

Fills up info with information about timesteps and timerange.

◆ GetPartitionedFiles()

virtual bool vtkFileSeriesHelper::GetPartitionedFiles ( )

virtual

Returns true if the file series is a series of partitions rather than a series of timesteps.

◆ GetActiveFiles()

std::vector< std::string > vtkFileSeriesHelper::GetActiveFiles ( vtkInformation * outInfo ) const

Returns the list of files to read on current rank to satisfy the request.

Requested time and piece information is obtained from outInfo. If outInfo has not piece information, however, than this->Controller is used.

Parameters

outInfo vtkInformation object with UPDATE_* keys that indicate the requested time and piece information.
