// .NAME vtkTableExtentTranslator - Extent translation through lookup table.
// .SECTION Description
// vtkTableExtentTranslator provides a vtkExtentTranslator that is
// programmed with a specific extent corresponding to each piece
// number. Readers can provide this to an application to allow the
// pipeline to execute using the same piece breakdown that is provided
// in the input file.

// Description:
// Set the number of pieces into which the whole extent will be
// split. If this is 1 then the whole extent will be returned. If
// this is more than the number of pieces in the table then the
// extra pieces will be empty data. If this is more than one but
// less than the number of pieces in the table then only this many
// pieces will be returned (FIXME).

// Set the real number of pieces in the extent table.

// outside the boundaries of the piece's file.
