Class Ret4<A,​B,​C,​D>

  • Type Parameters:
    A - The type of the first member-field ('a').
    B - The type of the second member-field ('b').
    C - The type of the third member-field ('c').
    D - The type of the last member-field ('d').
    All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable
    public class Ret4<A,​B,​C,​D>
extends RetN
implements java.io.Serializable, java.lang.Cloneable
    This simple generic-class allows a function to return four objects as a result, instead of just one. This is not always so useful, and can make code confusing. However there are some instances where the only alternative would be to create an entirely new class/object, when only a single method result would use that object.

        🡇  ⇈  ⮫ 
        protected static final long serialVersionUID
        This fulfils the SerialVersion UID requirement for all classes that implement Java's interface java.io.Serializable. Using the Serializable Implementation offered by java is very easy, and can make saving program state when debugging a lot easier. It can also be used in place of more complicated systems like "hibernate" to store data as well.
