Interface TypeWrapper

All Superinterfaces:
Serializable
All Known Implementing Classes:
AbstractSimpleTypeWrapper, BooleanTypeWrapper, ColorTypeWrapper, EnumTypeWrapper, NumberTypeWrapper, StringTypeWrapper, TLIListTypeWrapper
public interface TypeWrapper extends Serializable
Encapsulates information about a parameter's value type and how values should be converted between strings and the appropriate object instances.

This allows elimination of an additional "evil" if-elseif...else" pattern.
