      Deprecated, for removal: This API element is subject to removal in a future version.
      Adds all elements from the supplied iteration to the specified collection. If the supplied iteration is an instance of CloseableIteration it is automatically closed after consumption.
      Parameters:
      iter - An iteration containing elements to add to the container. If the iteration is an instance of CloseableIteration it is automatically closed after consumption.
      collection - The collection to add the elements to.
      Returns:
      The collection object that was supplied to this method.
      Throws:
      X

      Adds all elements from the supplied CloseableIteration to the specified collection then closes the CloseableIteration.
      Parameters:
      iter - A CloseableIteration containing elements to add to the container.
      collection - The collection to add the elements to.
      Returns:
      The collection object that was supplied to this method.
      Throws:
      X

    • stream

      @Deprecated(since="4.1.0", forRemoval=true) public static <T> Stream<T> stream(Iteration<T,? extends Exception> iteration)
      Deprecated, for removal: This API element is subject to removal in a future version.
      Get a sequential Stream with the supplied Iteration as its source. If the source iteration is a CloseableIteration, it will be automatically closed by the stream when done. Any checked exceptions thrown at any point during stream processing will be propagated wrapped in a RuntimeException.
      Parameters:
      iteration - a source Iteration for the stream.
      Returns:
      a sequential Stream object which can be used to process the data from the source iteration.

    • stream

      public static <T> Stream<T> stream(CloseableIteration<T,? extends Exception> iteration)
      Deprecated.
      Get a sequential Stream with the supplied CloseableIteration as its source. The source iteration will be automatically closed by the stream when done. Any checked exceptions thrown at any point during stream processing will be propagated wrapped in a RuntimeException.
      Parameters:
      iteration - a source CloseableIteration for the stream.
      Returns:
      a sequential Stream object which can be used to process the data from the source iteration.
