    • boundary

      public Geometry boundary()
      The boundary of this geometryCollection, made of the boundary of each element
      Returns:
      a line string which defines the boundary of the current geometry.

    • validate

      public static Geometry validate(GeometryCollection geometryCollection)
      Validates all geometries in the specified GeometryCollection, removing all geometries that aren't georeferenced. If the remaining geometry list is empty, then null is returned.
      Parameters:
      geometryCollection - the geometry collection to validate.
      Returns:
      the validated geometry collection, of null if the specified geometry collection doesn't contain any valid geometries.

    • fit

      returns the best type of collection for the element in the List
      Parameters:
      list -
