@Deprecated(since="4.1.0") public class Iterations extends Object
Deprecated.
This class consists exclusively of static methods that operate on or return Iterations. It is the Iteration-equivalent of java.util.Collections.

  • Constructor Details

    • Iterations

      public Iterations()
      Deprecated.

  • Method Details

    • asList

      public static <E, X extends Exception> List<E> asList(CloseableIteration<? extends E> iter)
      Deprecated.
      Get a List containing all elements obtained from the specified iteration.
      Parameters:
      iter - the CloseableIteration to get the elements from
      Returns:
      a List containing all elements obtained from the specified iteration.

    • asSet

      public static <E, X extends Exception> Set<E> asSet(CloseableIteration<? extends E> iter)
      Deprecated.
      Get a Set containing all elements obtained from the specified iteration.
      Parameters:
      iter - the CloseableIteration to get the elements from
      Returns:
      a Set containing all elements obtained from the specified iteration.

    • addAll

      public static <E, X extends Exception, C extends Collection<E>> C addAll(CloseableIteration<? extends E> iter, C collection)
      Deprecated.
      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.

    • stream

      public static <T> Stream<T> stream(CloseableIteration<T> 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.

    • toString

      public static <X extends Exception> String toString(CloseableIteration<?> iteration, String separator)
      Deprecated.
      Converts a CloseableIteration to a string by concatenating all the string representations of objects in the iteration, divided by a separator.
      Parameters:
      iteration - A CloseableIteration over arbitrary objects that are expected to implement Object.toString().
      separator - The separator to insert between the object strings.
      Returns:
      A String representation of the objects provided by the supplied iteration.

    • toString

      public static <X extends Exception> void toString(CloseableIteration<?> iteration, String separator, StringBuilder sb) throws X
      Deprecated.
      Converts a CloseableIteration to a string by concatenating all the string representations of objects in the iteration, divided by a separator.
      Parameters:
      iteration - A CloseableIteration over arbitrary objects that are expected to implement Object.toString().
      separator - The separator to insert between the object strings.
      sb - A StringBuilder to append the iteration string to.
      Throws:
      X

    • asSet

      public static <E, X extends Exception> Set<E> asSet(CloseableIteration<? extends E> iteration, Supplier<Set<E>> setMaker)
      Deprecated.
      Get a Set containing all elements obtained from the specified iteration.
      Parameters:
      iteration - the iteration to get the elements from
      setMaker - the Supplier that constructs a new set
      Returns:
      a Set containing all elements obtained from the specified iteration.
