Interface CheckedFunction<T,R,E extends Exception>

Type Parameters:

E - type of checked exception possibly thrown by the implementation. You can use e.g. RuntimeException if particular implementation does not throw any checked exceptions.

public interface CheckedFunction<T,R,E extends Exception>

A variant of Function that allows checked exceptions.

Unless you need to expose checked exceptions in your API, you should use the original interface. However, when you're unlucky enough and you have to deal with IOException, SQLException or any other checked exception, this class might come useful.
