    • Constructor Detail

      • IfClosure

        public IfClosure​(Predicate<? super E> predicate,
                         Closure<? super E> trueClosure)
        Constructor that performs no validation. Use ifClosure if you want that.

        This constructor creates a closure that performs no action when the predicate is false.

        Parameters:
        predicate - predicate to switch on, not null
        trueClosure - closure used if true, not null
        Since:
        3.2
      • IfClosure

        public IfClosure​(Predicate<? super E> predicate,

                         Closure<? super E> falseClosure)
        Constructor that performs no validation. Use ifClosure if you want that.
        Parameters:
        predicate - predicate to switch on, not null
        trueClosure - closure used if true, not null
        falseClosure - closure used if false, not null
    • Method Detail

      • ifClosure

        public static <E> Closure<E> ifClosure​(Predicate<? super E> predicate,
                                               Closure<? super E> trueClosure)
        Factory method that performs validation.

        This factory creates a closure that performs no action when the predicate is false.

        Type Parameters:
        E - the type that the closure acts on
        Parameters:
        predicate - predicate to switch on
        trueClosure - closure used if true
        Returns:
        the if closure
        Throws:
        NullPointerException - if either argument is null
        Since:
        3.2

        Parameters:
        predicate - predicate to switch on
        trueClosure - closure used if true
        falseClosure - closure used if false
        Returns:
        the if closure
        Throws:
        NullPointerException - if any argument is null
