Method Detail

resolveTypeParameters

public static List<org.jboss.jandex.Type> resolveTypeParameters(org.jboss.jandex.DotName input,
                                                                org.jboss.jandex.DotName target,
                                                                org.jboss.jandex.IndexView index)

Returns the captured generic types of an interface given a class that at some point in the class hierarchy implements the interface. The list contains the types in the same order as they are generic parameters defined on the interface A result is only returned if and only if all the generics where captured. If any of them where not defined by the class an exception is thrown. Also note that all parts of the class/interface hierarchy must be in the supplied index As an example, imagine the following class:

 class MyList implements List<String> {
     ...
 }

 

If we call

 JandexUtil.resolveTypeParameters(DotName.createSimple(MyList.class.getName()),
         DotName.createSimple(List.class.getName()), index)

 

then the result will contain a single element of class ClassType whose name() would return a DotName for String
