How do I get a class instance of generic type T?

Question

I have a generics class, Foo. In a method of Foo, I want to get the class instance of type T, but I just can\'t call T.

Answer 1

It's possible:

class Foo {
  Class clazz = (Class) DAOUtil.getTypeArguments(Foo.class, this.getClass()).get(0);
}

You need two functions from hibernate-generic-dao/blob/master/dao/src/main/java/com/googlecode/genericdao/dao/DAOUtil.java.
