Class TypeReference<T>

java.lang.Object
org.osgi.util.converter.TypeReference<T>
Type Parameters:
T - The target type for the conversion.
@ConsumerType public class TypeReference<T> extends Object
An object does not carry any runtime information about its generic type. However sometimes it is necessary to specify a generic type, that is the purpose of this class. It allows you to specify an generic type by defining a type T, then subclassing it. The subclass will have a reference to the super class that contains this generic information. Through reflection, we pick this reference up and return it with the getType() call. 
 List<String> result = converter.convert(Arrays.asList(1, 2, 3))
                .to(new TypeReference<List<String>>() {
                });
