Interface TypeInfo

All Known Implementing Classes:

DefaultTypeInfo, ReflectionTypeInfo, SimpleTypeInfo

public interface TypeInfo

Neither Class nor Type really do it for passing generic type information around. Type isn't guaranteed to work, and Class can't tell you any thing about the types. TypeInfo allows us to annotate the type information when we know more than the JVM.

Method Summary

java.lang.Class<?>	getPrimaryType() The We'd like to just pass around a Class, but that doesn't hold generic information, so this gets us the basic level of data.
