Combined Class/Property

The Combined Class/Property uses each item’s class to decide whether it is included or not. The possible classes are LineString, Point, Polygon etc.

The Combined Class/Property is similar to the Class Filter but in addition each node in the class tree (e.g. LineString, Point) may have a partial clause (which is an expression) allowing further filtering. e.g. to find all of the Polygon items which are defined anti-clockwise.

Note: See Property Expression Syntax for details.
