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.
