      • isIterable

        public static boolean isIterable​(@Nullable
                                 java.lang.Object object)
        Checks if the given object is an instance of Iterable.

        Example Usage

        
 List<String> list = Arrays.asList("a", "b", "c");
 boolean result1 = IterableUtils.isIterable(list);     // true
 boolean result2 = IterableUtils.isIterable("string"); // false
 boolean result3 = IterableUtils.isIterable(null);     // false
        Parameters:
        object - the object to check
        Returns:
        true if the object is an instance of Iterable, false otherwise

      • isIterable

        public static boolean isIterable​(@Nullable
                                 java.lang.Class<?> clazz)
        Checks if the given class is assignable from Iterable.

        Example Usage

        
 boolean result1 = IterableUtils.isIterable(List.class);  // true
 boolean result2 = IterableUtils.isIterable(String.class); // false
 boolean result3 = IterableUtils.isIterable(null);        // false
        Parameters:
        clazz - the class to check
        Returns:
        true if the class is assignable from Iterable, false otherwise

      • iterate

        public static <E> void iterate​(@Nullable
                               java.lang.Iterable<E> elements,
                               @Nonnull
                               java.util.function.Consumer<E> elementConsumer)
        Iterates over the given Iterable and applies the provided Consumer to each element.

        Example Usage

        
 List<String> list = Arrays.asList("a", "b", "c");
 IterableUtils.iterate(list, System.out::println);
 // Output:
 // a
 // b
 // c
        Type Parameters:
        E - the type of elements in the Iterable
        Parameters:
        elements - the Iterable to iterate over
        elementConsumer - the Consumer to apply to each element

      • forEach

        public static <E> void forEach​(@Nullable
                               java.lang.Iterable<E> elements,
                               @Nonnull
                               java.util.function.Consumer<E> elementConsumer)
        Iterates over the given Iterable and applies the provided Consumer to each element.

        This method is equivalent to iterate(Iterable, Consumer).

        Example Usage

        
 List<String> list = Arrays.asList("a", "b", "c");
 IterableUtils.forEach(list, System.out::println);
 // Output:
 // a
 // b
 // c
        Type Parameters:
        E - the type of elements in the Iterable
        Parameters:
        elements - the Iterable to iterate over
        elementConsumer - the Consumer to apply to each element

        iterate(Iterable, Consumer)
