Detailed Description
Models a collection of Point objects.
Any collection of Points is a valid MultiPoint.
Constructor & Destructor Documentation
◆ MultiPoint()
|
protected |
Constructs a MultiPoint.
- Parameters
-
newPoints the Points for thisMultiPoint, ornullor an empty array to create the empty geometry. Elements may be emptyPoints, but notnulls.
Constructed object will take ownership of the vector and its elements.
- Parameters
-
newFactory The GeometryFactory used to create this geometry Caller must keep the factory alive for the life-time of the constructed MultiPoint.
Member Function Documentation
◆ getBoundary()
|
overridevirtual |
Gets the boundary of this geometry.
Zero-dimensional geometries have no boundary by definition, so an empty GeometryCollection is returned.
- Returns
- an empty GeometryCollection
- See also
- Geometry::getBoundary
