[vtk-developers] [proposal] Purge() method for vtkTable

[Stanton, Eric T]

vtkTable uses vtkFieldData to store its columns (accessible via vtkTable::GetRowData()). vtkFieldData also has a Reset() method which just calls Reset() on its internal arrays.

Note also that Reset() is used in the data arrays (vtkAbstractArray) to reset containers to an empty state without freeing memory.

Hello,

I am proposing to add a Purge() method to vtkTable for the following reason: currently, there is no direct way to clear the contents
of such a table while preserving the existing column structure. Calling Delete() results in having to re-create the said structure, which
is both inconvenient and inefficient.

The proposed method would address this issue by emptying columns while preserving the table structure.

Please let me know what you think.

Thank you,
Philippe
