Interface ValueTransform

public interface ValueTransform

Provides a common interface for defining conversions between raw and physical values. A raw value might be a value that you get directly from a channel access call. The end user may want a processed value (e.g. convert current to field). ValueTransform provides a common interface in XAL for such processing.
