Class GeometryDescriptorBuilder

java.lang.Object
  com.tensegrity.composite.geometry.persistence.GeometryDescriptorBuilder

All Implemented Interfaces:

Builder

public class GeometryDescriptorBuilder

extends java.lang.Object

implements Builder

The GeometryDescriptorBuilder creates an instance of GeometryDescriptor from an AttributeList. It uses the GeometryDescriptorItemBuilder to reconstruct the GeometryDescriptorItem's. Coordinates are restored by using the CoordinateSystemPool.
