Class Tuple3<A,​B,​C>

  • Type Parameters:
    A - The object a type.
    B - The object b type.
    C - The object c type.
    public class Tuple3<A,​B,​C>
extends Tuple2<A,​B>
    Three-object holder. The three objects are called by convention, a, b and c.
    Implements equals(Object) and hashCode(), based on the three objects.
    If two tuples tup1 and tup2 have the same objects, but in different order, tup1.equals(tup2) may be false and tup1.hashCode() == tup2.hashCode() may be false.
    Example:
    Tuple3.newInstance(1, 2, 3).equals(Tuple3.newInstance(3, 2, 1)) is false.
    Tuple3.newInstance(1, 2, 3).hashCode() == Tuple3.newInstance(3, 2, 1).hashCode() is false.
    This holder accepts null values.
