java.lang.Object

org.mule.runtime.core.internal.streaming.object.iterator.ConsumerStreamingIterator<T>

All Implemented Interfaces:

Closeable, AutoCloseable, Iterator<T>, org.mule.runtime.api.streaming.HasSize, StreamingIterator<T>

public class ConsumerStreamingIterator<T>
extends Object
implements StreamingIterator<T>

Implementation of StreamingIterator that takes its elements from a Consumer.

Closing this iterator will cause the underlying consumer to be closed. If for any reason the underlying consumer gets closed (either because this iterator closed it or some other reason), then this iterator will consider that it has no more items.
