ObjectGeometryCoordinateSequenceTransformer
public class GeometryCoordinateSequenceTransformer
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.
Constructor Summary | |
---|---|
GeometryCoordinateSequenceTransformer()
Creates a transformer which uses the CoordinateSequenceFactory
of the source geometries. |
|
GeometryCoordinateSequenceTransformer(CoordinateSequenceTransformer transformer)
Creates a transformer which uses a client-specified CoordinateSequenceTransformer . |
Method Summary | |

void |
setCoordinateReferenceSystem(CoordinateReferenceSystem crs)
Sets the target coordinate reference system. |
void |
setMathTransform(MathTransform transform)
Sets the math transform to be used for transformation |
Geometry |
transform(Geometry g)
Applies the transform to the provided geometry, creating a new transformed geometry. |

public GeometryCoordinateSequenceTransformer()
CoordinateSequenceFactory
of the source geometries.
public GeometryCoordinateSequenceTransformer(CoordinateSequenceTransformer transformer)
CoordinateSequenceTransformer
.
WARNING: The CoordinateSequenceTransformer must use
the same CoordinateSequenceFactory
as the output
GeometryFactory, so that geometries are constructed consistently.
