- - ### Constructor Detail

    - #### ChainedClosure

          public ChainedClosure(Closure<? super E>... closures)

      Constructor that performs no validation. Use `chainedClosure` if you want that.
      Parameters:
        `closures` - the closures to chain, copied, no nulls

  - ### Method Detail

    - #### chainedClosure

          public static <E> Closure<E> chainedClosure(Closure<? super E>... closures)

      Factory method that performs validation and copies the parameter array.
      Type Parameters:
        `E` - the type that the closure acts on
      Parameters:
        `closures` - the closures to chain, copied, no nulls
      Returns:
        the `chained` closure
      Throws:
        `NullPointerException` - if the closures array is null
        `NullPointerException` - if any closure in the array is null

    - #### chainedClosure

          public static <E> Closure<E> chainedClosure(Collection<? extends Closure<? super E>> closures)

      Create a new Closure that calls each closure in turn, passing the result into the next closure. The ordering is that of the iterator() method on the collection.
      Type Parameters:
        `E` - the type that the closure acts on
      Parameters:
        `closures` - a collection of closures to chain
      Returns:
        the `chained` closure
      Throws:
        `NullPointerException` - if the closures collection is null
        `NullPointerException` - if any closure in the collection is null

    - #### execute

          public void execute(E input)

      Execute a list of closures.
      Specified by:
        `execute` in interface `Closure<E>`
      Parameters:
        `input` - the input object passed to each closure

    - #### getClosures

          public Closure<? super E>[] getClosures()

      Gets the closures.
      Returns:
        a copy of the closures
