@Deprecated(since="4.1.0") public abstract class ExceptionConvertingIteration<E,X extends RuntimeException> extends AbstractCloseableIteration<E>

to do the conversion.

  • Constructor Details

    • ExceptionConvertingIteration

      protected ExceptionConvertingIteration(CloseableIteration<? extends E> iter)
      Deprecated.
      Creates a new ExceptionConvertingIteration that operates on the supplied iteration.

      iter - The Iteration that this ExceptionConvertingIteration operates on, must not be null.

  • Method Details

    • convert

      protected abstract X convert(RuntimeException e)

      Deprecated.
      Returns the next element from the wrapped Iteration.
      Throws:

      Throws:
      UnsupportedOperationException - If the wrapped Iteration does not support the remove operation.
