  • Constructor Details

    • CloseableIteratorIteration

      public CloseableIteratorIteration()
      Creates an uninitialized CloseableIteratorIteration, needs to be initialized by calling setIterator(Iterator) before it can be used.

      public CloseableIteratorIteration(Iterator<? extends E> iter)
      Creates a CloseableIteratorIteration that wraps the supplied iterator.

  • Method Details

    • setIterator

      protected void setIterator(Iterator<? extends E> iter)

    • hasIterator

      protected boolean hasIterator()

    • hasNext

      public boolean hasNext() throws X
      Description copied from interface: Iteration

      public void remove() throws X
