      • isNull

        public static boolean isNull​(java.lang.Object obj)
        Returns true if the provided reference is null otherwise returns false.
        Parameters:
        obj - a reference to be checked against null
        Returns:
        true if the provided reference is null otherwise false

      • isNull

        public static void isNull​(java.lang.Object obj,
                          ExecutableFunction executableFunction)
        Execute code if the provided reference is null.
        Parameters:
        obj - a reference to be checked against null
        executableFunction - lambda function given executed if the provided reference is null.

      • nonNull

        public static boolean nonNull​(java.lang.Object obj)
        Returns true if the provided reference is non-null otherwise returns false.
        Parameters:
        obj - a reference to be checked against null
        Returns:
        true if the provided reference is non-null otherwise false

      • nonNull

        public static void nonNull​(java.lang.Object obj,
                           ExecutableFunction executableFunction)
        Execute code if the provided reference is non-null.
        Parameters:
        obj - a reference to be checked against null
        executableFunction - lambda function given executed if the provided reference is non-null.

      • equals

        public static boolean equals​(java.lang.Object a,
                             java.lang.Object b)
        Returns true if the arguments are equal to each other and false otherwise. Consequently, if both arguments are null, true is returned and if exactly one argument is null, false is returned. Otherwise, equality is determined by using the equals method of the first argument.
        Parameters:
        a - an object
        b - an object to be compared with a for equality
        Returns:
        true if the arguments are equal to each other and false otherwise
