util
Interface Predicate<T>

Type Parameters:

T - The argument type of the function.

public interface Predicate<T>

A function returning a boolean value. Used by methods of the Functional class.

For instance, one could create a predicate to tell if a given integer is even or odd:

      isEven = new Predicate<Integer>() {
          boolean f(int n) {
              return f % 2 == 0;
          }
      }
  

This predicate could then be passed to methods like Functional.separate(Collection, Predicate, Collection, Collection) (see the example there).
