Geometry type.
Abstract base class for the PolylineBuilder and PolygonBuilder classes.

Syntax
public abstract class MultipartBuilder<T> : GeometryBuilder<T>, System.IDisposable  
where T: Multipart
Public MustInherit Class MultipartBuilder(Of T As Multipart) 
   Inherits GeometryBuilder(Of T)
   Implements System.IDisposable 
Type Parameters
T
Geometry type.
Remarks

Use the MultipartBuilder class to to create and/or modify a base Multipart shape. The builder is best suited for editing workflows where the user may be adding, inserting or removing parts of a Multipart geometry interactively. A Multipart is based upon the parent Geometry class. The Geometry class is immutable which means that you can not change its shape once it is created. Hence, the MultipartBuilder provides the way to make changes when working with a Multipart. Use the PolylineBuilder.ToGeometry or PolygonBuilder.ToGeometry method to get the Multipart from the builder.
