MultipointBuilder class final
The multipoint builder allows you to create and modify multipoint geometries.
Multipoint geometries represent an ordered collection of points. They can be used as the geometry of features and graphics, or as input or output for spatial operations. For features that consist of a very large number of points that share the same set of attribute values, multipoints may be more efficient to store and analyze in a geodatabase compared to using multiple point features.
A Multipoint is composed of a single read-only ArcGISPoint collection. Use GeometryBuilder.toGeometry to return the Multipoint from the MultipointBuilder.
