    • equals

      public static <T, C> boolean equals(T object, C value, Object to, Function<T,C> getter)
      Compare only one value that belongs to class and determines equality
      Type Parameters:
      T - type of current object
      C - type of compared values
      Parameters:
      object - the current object (~ this)
      value - the value of current object
      to - the object to compare with
      getter - the getter to obtain value from compared object

    • equals

      public static <T> boolean equals(T object, Object to, BiPredicate<T,T> equals)
      Compare objects without boilerplate initial statements like (object == this) and (getClass() != to.getClass())
      Type Parameters:
      T - type of objects to compare
      Parameters:
      object - the current object (this)
      to - the object to compare with
      equals - the predicate which determines equality
      Returns:
      true if objects are the same type and fulfils the predicate
