sequence functions - ObjectVision/GeoDMS GitHub Wiki

Sequence functions are used to process data items with one-dimensional sequences

See also:

  • Sequence2points - all vertices of each arc/polygon as separate points
  • Points2sequence - constructs arc/polygon from vertices
  • first_point - first point of each sequence
  • last_point - last point of each sequence
  • split_piped_string - split strings by pipe character
  • split_multi_linestring - split multi-linestrings at undefined points
  • points2arc - as Points2sequence, resulting in arc composition
  • sequence_element_count - number of points of each sequence
  • points2sequence_p - Points2sequence form with only a point argument: one sequence in domain order
  • points2sequence_ps - Points2sequence form with (point, sequence_rel) arguments
  • points2sequence_po - Points2sequence form with (point, ordinal permutation) arguments: one ordered sequence
  • points2sequence_pso - Points2sequence form with (point, sequence_rel, ordinal) arguments
  • points2arc_p, points2arc_ps, points2arc_po, points2arc_pso - the same argument-forms of points2arc
  • points2polygon_p, points2polygon_ps, points2polygon_po, points2polygon_pso - the same argument-forms of points2polygon
  • points2multi_point_p, points2multi_point_ps, points2multi_point_po, points2multi_point_pso - the same argument-forms of points2multi_point
  • sequence2points_uint64 - is the Sequence2points variant with a uint64 result domain
  • split_multi_numberstring - as split_multi_linestring for numeric sequences: splits them at null elements
