Class ShapeAdapter

java.lang.Object
org.apache.sis.internal.referencing.j2d.AbstractShape
org.apache.sis.internal.feature.jts.ShapeAdapter
All Implemented Interfaces:
Shape, Serializable
final class ShapeAdapter extends AbstractShape implements Serializable
A thin wrapper that adapts a JTS geometry to the Shape interface so that the geometry can be used by Java 2D without copying coordinate values. This class does not cache any value; if the JTS geometry is changed, the modifications will be immediately visible in this Shape.

1.2

    • SMALL_FACTORY

      private static final org.locationtech.jts.geom.GeometryFactory SMALL_FACTORY
      A lightweight JTS geometry factory using the default CoordinateArraySequenceFactory. This factory is inefficient for large geometries (it consumes more memory) but is a little bit more straightforward for geometry with few coordinates such as a point or a rectangle, because it stores the Coordinate[]. Used for contains(…) and intersects(…) implementations only.
