Constructor Detail

CoordinateTransformation

public CoordinateTransformation(SpatialReference src,
                        SpatialReference dst)

Create transformation object.

Input spatial reference system objects are assigned by copy (calling clone() method) and no ownership transfer occurs.

Parameters:

src - source spatial reference system.

dst - target spatial reference system.

Method Detail

delete

public void delete()
