Interface WildcardType

All Superinterfaces:
AnnotatedConstruct, TypeMirror

public interface WildcardType extends TypeMirror
Represents a wildcard type argument. Examples include:

   ?
   ? extends Number
   ? super T
 

A wildcard may have its upper bound explicitly set by an extends clause, its lower bound explicitly set by a super clause, or neither (but not both).
