Method Detail

setOf

@SafeVarargs
public static <D> Set<D> setOf(D... values)

splitToSet

public static Set<String> splitToSet(String value,
                                     String splitter)

iterator

public static <D> Iterator<D> iterator(Iterable<D> iterable)

Transform Iterable to Iterator (simply by calling it's iterator() method). Keep in mind the difference between iterator() and queueIterator applied on Queue. iterator will iterate current collection in the queue, and throw exception on content change, but queueIterator takes into account new elements added to the queue while iterating.

Type Parameters:

D - Type of the elements in the iterable.

Parameters:

iterable - Any iterable.

Returns:

Iterator.

queueIterator

public static <D> Iterator<D> queueIterator(Queue<D> queue)

Transform Queue to Iterator. It provides custom implementation, that takes into account changes (new elements added) during the iteration. Keep in mind the difference between iterator() and queueIterator applied on Queue. iterator will iterate current collection in the queue, and throw exception on content change, but queueIterator takes into account new elements added to the queue while iterating.

Type Parameters:

D - Type of the elements in the iterable.

Parameters:

queue - Any iterable.

Returns:

Iterator.

blockingQueueIterator

public static <D> Iterator<D> blockingQueueIterator(BlockingQueue<D> queue,
                                                    long timeout)

Adapt BlockingQueue to Iterator. It uses blocking poll() when attempt to get next element, so it allows testing of asynchronous streams, making the iterable check to wait for future updates within given timeout.

Type Parameters:

D - Type of the elements in the iterable.

Parameters:

queue - Blocking queue.

timeout - timeout in milliseconds indicating end of the queue.

Returns:

Iterator.
