Answer 1

This has been answered in previous questions. Basically, there are 2 options:

1. Pass the Type in from the calling site. The calling code will use TypeToken or whatever to construct it.
2. Construct a Type corresponding to the parameterized type yourself. This will require you to write a class that implements ParameterizedType
