    All Methods Instance Methods Abstract Methods Concrete Methods
    Modifier and Type | Method and Description
    --- | ---
    `protected void` | `handleClose()` Closes this Iteration and also closes the wrapped Iteration if it is a `CloseableIteration`.
    `boolean` | `hasNext()` Checks whether the wrapped Iteration contains more elements, closing this Iteration when this is not the case.
    `E` | `next()` Returns the next element from the wrapped Iteration.
    `void` | `remove()` Removes the last element that has been returned from the wrapped Iteration.
    `protected abstract void` | `throwInterruptedException()` If the iteration is interrupted by its time limit, this method is called to generate and throw the appropriate exception.

      Throws:
        `X`
        `X extends Exception`

    - #### next

          public E next()
                 throws X extends Exception

      Overrides:
        `next` in class `IterationWrapper<E,X extends Exception>`
      Returns:
        the next element in the iteration.
      Throws:
        `X extends Exception`

    - #### remove

      Specified by:
        `remove` in interface `Iteration<E,X extends Exception>`
      Overrides:
        `remove` in class `IterationWrapper<E,X extends Exception>`
      Throws:
        `X extends Exception`

    - #### handleClose

          protected void handleClose()
                              throws X extends Exception

      Description copied from class: `IterationWrapper`
      Closes this Iteration and also closes the wrapped Iteration if it is a `CloseableIteration`.
      Overrides:
        `handleClose` in class `IterationWrapper<E,X extends Exception>`
      Throws:
        `X`
        `X extends Exception`
