A {@code TransferQueue} may be useful for * example in message passing applications in which producers * sometimes (using method {@link #transfer}) await receipt of * elements by consumers invoking {@code take} or {@code poll}, while * at other times enqueue elements (via method {@code put}) without * waiting for receipt. * {@linkplain #tryTransfer(Object) Non-blocking} and * {@linkplain #tryTransfer(Object,long,TimeUnit) time-out} versions of * {@code tryTransfer} are also available. * A {@code TransferQueue} may also be queried, via {@link * #hasWaitingConsumer}, whether there are any threads waiting for * items, which is a converse analogy to a {@code peek} operation. * * <p>Like other blocking queues, a {@code TransferQueue} may be * capacity bounded. If so, an attempted transfer operation may * initially block waiting for available space, and/or subsequently * block waiting for reception by a consumer. Note that in a queue * with zero capacity, such as {@link SynchronousQueue}, {@code put} * and {@code transfer} are effectively synonymous. * * <p>This interface is a member of the * <a href="{@docRoot}/../technotes/guides/collections/index.html"> * Java Collections Framework</a>. * * @since 1.7 * @author Doug Lea * @param <E> the type of elements held in this collection */ public interface TransferQueue<E> extends BlockingQueue Other Java examples (source code examples)Here is a short list of links related to this Java TransferQueue.java source code file: |
