The new functionality created so far did not require looking at the logical structure of an SDO_GEOMETRY
object, as described by the SDO_ELEM_INFO
attribute. Understanding and being able to process the contents of this VARRAY
is important, when developing or implementing more complex functionality.
The SDO_ELEM_INFO
(see "2.2.4 SDO_ELEM_INFO
", in the Oracle® Spatial Developer's Guide 11g Release 2 (11.2)) attribute is organized as a set of elements, each having three values or members. Each member of a triplet has a name: SDO_OFFSET
(
actually SDO_STARTING_OFFSET)
, SDO_ETYPE
, and SDO_INTERPRETATION
. These members are described in the "Section 2.2.4 SDO_ELEM_INFO
", in the Oracle® Spatial Developer's Guide 11g Release 2 (11.2) (edited) by the following Table:
