[vtkusers] vtkDoubleArray -- you can set the number of values but you can't get the number of values?

[Thompson, David C]

You may call GetMaxId(), which returns the number of values minus 1 (since
IDs start at 0).

Subject: [vtkusers] vtkDoubleArray -- you can set the number of values but you can't get the number of values?

I've been staring for some time at the Doxygen man pages for
vtkDoubleArray and vtkDataArray.  It seems that there is a member
function vtkDoubleArray::SetNumberOfValues(), but no corresponding
vtkDoubleArray::GetNumberOfValues().

This seems to indicate that you have to make sure that you never try
to read out more values than you've put in to the array, because
there's no way to check this.

Or am I missing something?
