Selection functions - ObjectVision/GeoDMS GitHub Wiki

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_with_org_rel - is the select_with_org_rel variant with a uint8 result domain
• select_uint16_with_org_rel - is the select_with_org_rel variant with a uint16 result domain
• select_uint32_with_org_rel - is the select_with_org_rel variant with a uint32 result domain
• 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_with_attr_by_org_rel - is the select_with_attr_by_org_rel variant with a uint8 result domain
• select_uint16_with_attr_by_org_rel - is the select_with_attr_by_org_rel variant with a uint16 result domain
• select_uint32_with_attr_by_org_rel - is the select_with_attr_by_org_rel variant with a uint32 result domain
• 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_with_attr_by_cond - is the select_with_attr_by_cond variant with a uint8 result domain
• select_uint16_with_attr_by_cond - is the select_with_attr_by_cond variant with a uint16 result domain
• select_uint32_with_attr_by_cond - is the select_with_attr_by_cond variant with a uint32 result domain
• 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_with_org_rel_with_attr_by_cond - is the select_with_org_rel_with_attr_by_cond variant with a uint8 result domain
• select_uint16_with_org_rel_with_attr_by_cond - is the select_with_org_rel_with_attr_by_cond variant with a uint16 result domain
• select_uint32_with_org_rel_with_attr_by_cond - is the select_with_org_rel_with_attr_by_cond variant with a uint32 result domain
• select_uint64_with_org_rel_with_attr_by_cond - is the select_with_org_rel_with_attr_by_cond variant with a uint64 result domain
• select_uint8_16_32_64_with_org_rel_with_attr_by_cond - versions of the select_with_org_rel_with_attr_by_cond function, resulting in a unit with the explicit value type

Note: select_data is replaced by collect_by_cond

• select_uint8 - is the select variant with a uint8 result domain (domain only, no org_rel or attributes)
• select_uint16 - is the select variant with a uint16 result domain
• select_uint32 - is the select variant with a uint32 result domain
• select_uint64 - is the select variant with a uint64 result domain
• select_uint64_with_org_rel - is the select_with_org_rel variant with a uint64 result domain
• select_uint64_with_attr_by_cond - is the select_with_attr_by_cond variant with a uint64 result domain
• select_uint64_with_attr_by_org_rel - is the select_with_attr_by_org_rel variant with a uint64 result domain
