Selection functions

Selection functions are used to create new domain units with selection of elements from other domain units.

For an overview of select operations and their recommended use, see https://github.com/ObjectVision/GeoDMS/wiki/selection-operator-comparison

  • select_with_org_rel or subset - configures a new unit, based on a condition
  • select_uint8_16_32_64_with_org_rel - versions of the select_with_org_rel function, resulting in a unit with the explicit value type
  • select and select_data OBSOLETE - similar to select_with_org_rel, but faster and less memory intensive in case of dense subsets
  • select_uint8_16_32_64 - versions of the select function, resulting in a unit with the explicit value type
  • select_with_attr_by_org_rel - similar to select_with_org_rel/subset, resulting in a unit and a set of attributes
  • select_uint8_16_32_64_with_attr_by_org_rel - versions of the select_with_attr_by_org_rel function, resulting in a unit with the explicit value type
  • select_with_attr_by_cond - similar to select_with_org_rel, resulting in a unit and a set of attributes
  • select_uint8_16_32_64_with_attr_by_cond - versions of the select_with_attr_by_cond function, resulting in a unit with the explicit value type
  • select_with_org_rel_with_attr_by_cond - similar to select_with_attr_by_cond: condition is used for all collections, but an org_rel is also produced
  • select_uint8_16_32_64_with_attr_by_cond - versions of the select_with_attr_by_cond function, resulting in a unit with the explicit value type

Note: select data is replaced by collect_by_cond
