public interface DataTransform

Provides a mapping from a primitive transform to a ValueTransform. While ValueTransform provides the recognized means for transforming between raw and physical values it requires a transformation of ArrayValue which is a general wrapper for value types including primitives and arrays of primitives. Often this is invconvenient to code. It is often much more convenient to code with a particular primitive value type (e.g. double) and hence implement a more specific transform (e.g. DoubleTransform). DataTransform facilitates the conversion from the specific transform to the more general ValueTransform. DataTransform is referenced only in its subclasses.
