- All Implemented Interfaces:
    Closure<E>

      public class ForClosure<E>
      extends Object
      implements Closure<E>

  Closure implementation that calls another closure n times, like a for loop.

  WARNING: from v4.1 onwards this class will not be serializable anymore in order to prevent potential remote code execution exploits. Please refer to COLLECTIONS-580 for more details.

    - #### ForClosure

          public ForClosure(int count,
                            Closure<? super E> closure)

      Constructor that performs no validation. Use `forClosure` if you want that.
      Parameters:
        `count` - the number of times to execute the closure
        `closure` - the closure to execute, not null

  - ### Method Detail

    - #### forClosure

          public static <E> Closure<E> forClosure(int count,
                                                  Closure<? super E> closure)

      Factory method that performs validation.

      A null closure or zero count returns the `NOPClosure`. A count of one returns the specified closure.

      Type Parameters:
        `E` - the type that the closure acts on
      Parameters:
        `count` - the number of times to execute the closure
        `closure` - the closure to execute, not null
      Returns:
        the `for` closure

    - #### execute

          public void execute(E input)

      Executes the closure `count` times.
      Specified by:
        `execute` in interface `Closure<E>`
      Parameters:
        `input` - the input object

    - #### getClosure

          public Closure<? super E> getClosure()

      Gets the closure.
      Returns:
        the closure
      Since:
        3.1

    - #### getCount

          public int getCount()

      Gets the count.
      Returns:
        the count
