Class GeometryCoordinateSequenceTransformer

  • public class GeometryCoordinateSequenceTransformer
    extends Object
    Service object that takes a geometry and applies a MathTransform to the coordinates it contains, creating a new geometry as the transformed output.

    The standard usage pattern is to supply a MathTransform and @link CoordinateReferenceSystem} explicitly. The transform(Geometry) method can then be used to construct transformed geometries using the GeometryFactory and CoordinateSequenceFactory of the input geometry.

      • GeometryCoordinateSequenceTransformer

        public GeometryCoordinateSequenceTransformer()
        Creates a transformer which uses the CoordinateSequenceFactory of the source geometries.
      • GeometryCoordinateSequenceTransformer

        public GeometryCoordinateSequenceTransformer​(CoordinateSequenceTransformer transformer)
        Creates a transformer which uses a client-specified CoordinateSequenceTransformer.

        WARNING: The CoordinateSequenceTransformer must use the same CoordinateSequenceFactory as the output GeometryFactory, so that geometries are constructed consistently.

      • setMathTransform

        public void setMathTransform​(MathTransform transform)
        Sets the math transform to be used for transformation
      • setCoordinateReferenceSystem

        public void setCoordinateReferenceSystem​(CoordinateReferenceSystem crs)
        Sets the target coordinate reference system.

        This value is used to set the coordinate reference system of geometries after they have been transformed.

        crs - The target coordinate reference system.
      • transform

        public Geometry transform​(Geometry g)
                           throws TransformException
        Applies the transform to the provided geometry, creating a new transformed geometry.
        g - the geometry to transform
        a new transformed geometry
