Interface ICobolUnmarshalChoiceStrategy

public interface ICobolUnmarshalChoiceStrategy

This interface is used for custom choice selection at unmarshaling time. Unmarshaling means host data needs to be converted to Java types. When multiple alternatives are available (REDEFINES), custom code can provide the logic to determine which alternative should be chosen.
