WRAPPER_API DatumTransform()
WRAPPER_API DatumTransform(ClassType classType)
WRAPPER_API DatumTransform(const DatumTransform&source)
The DatumTransform constructor creates a new instance of the DatumTransform class. There are three signatures for this constructor.
The default constructor takes no arguments and produces a DatumTransform in which get_Class indicates Molodensky. The SourceCoordSys, TargetCoordSys, and Parameters need to be set before the DatumTransform can be used. For a description of the parameters needed by each type of DatumTransform, click on the link in the description column on the ClassType Enumeration page.
The second constructor takes a single argument that specifies the type of the DatumTransform according to the ClassType enumeration. Otherwise it is identical to the above.
The third constructor is a copy-constructor. It takes a single argument that is the DatumTransform that will be copied to construct the new DatumTransform.
