Detailed Description

exporter used by certain views to export data as CSV.

vtkCSVExporter can be used to generate comma-separated files. Unlike vtkCSVWriter, this class can generate a single CSV from multiple array collections. This avoids the need to generate of single large appended table. The multiple arrays together represent the complete tabular data that gets exported. The table can be split column-wise or row-wise between multiple arrays. The vtkCSVExporter provides two sets of APIs to handle the two cases. They cannot be mixed.

When exporting array instances split by columns, i.e. each array will have exactly same number of rows but different columns that are to be concatenated together, use the STREAM_COLUMNS mode. To use this mode, start writing by using vtkCSVExporter::Open(vtkCSVExporter::STREAM_COLUMNS) and then add each column using vtkCSVExporter::AddColumn. Finally, complete the export can generate the output using vtkCSVExporter::Close.

When exporting arrays that are split by rows, use the STREAM_ROWS mode. The arrays are provided as a part of vtkFieldData (or subclass). To begin exporting in this mode, use vtkCSVExporter::Open(vtkCSVExporter::STREAM_ROWS). Write the header using vtkCSVExporter::WriteHeader(vtkFieldData*) and the pass rows in order by using vtkCSVExporter::WriteData(vtkFieldData*) multiple times. Finally, close usingvtkCSVExporter::Close`.

In STREAM_ROWS mode, the exporter supports invalid / empty cells. When writing each column in WriteData call, for each column-name an vtkUnsignedCharArray with the name __vtkValidMask__{COLUMN_NAME} is looked up. If found, it's value is used to determine if that cell is to written out or not.

overridevirtual

Open the file and set mode in which the exporter is operating.

void vtkCSVExporter::Close ( )

overridevirtual

Closes the file cleanly.

Call this at the end to close the file and dump out any cached data.

Implements vtkAbstractChartExporter.

◆ Abort()

void vtkCSVExporter::Abort ( )

overridevirtual

Same as Close except deletes the file, if created.

This is useful to interrupt the exporting on failure.

Implements vtkAbstractChartExporter.

◆ WriteHeader()

overridevirtual

In STREAM_ROWS mode, use these methods to write column headers once using WriteHeader and then use WriteData as many times as needed to write out rows.

Implements vtkAbstractChartExporter.

◆ WriteData()

	)

overridevirtual

In STREAM_COLUMNS mode, use this method to add a column (yarray).

One can assign it a name different the the name of the array using yarrayname. If xarray is not nullptr, then is used as the row-id. This makes it possible to add multiple columns with varying number of samples. The final output will have empty cells for missing values.
