public class TypeReference<T> extends Object
T
. Java doesn't yet provide a way to
represent generic types, so this class does. Forces clients to create a
subclass of this class which enables retrieval the type information even at
runtime.
For example, to create a type literal for List<String>
, you can
create an empty anonymous inner class:
TypeReference<List<String>> list = new TypeReference<List<String>>() {};This syntax cannot be used to create type literals that have wildcard parameters, such as
Class<?>
or List<? extends CharSequence>
