Class AbstractPrefetchInputStreamReceiver<DATA extends Serializable>

java.lang.Object

org.refcodes.component.AbstractConnectable

org.refcodes.component.AbstractConnectableAutomaton

org.refcodes.io.AbstractDatagramsReceiver<DATA>

org.refcodes.io.AbstractPrefetchInputStreamReceiver<DATA>

Type Parameters:

DATA - The type of the datagram to be operated with.

All Implemented Interfaces:

Direct Known Subclasses:

PrefetchBidirectionalStreamConnectionTransceiver, PrefetchInputStreamConnectionReceiver

public abstract class AbstractPrefetchInputStreamReceiver<DATA extends Serializable>
extends AbstractDatagramsReceiver<DATA>

Abstract implementation of the DatagramsReceiver interface. As of the prefetching functionality, a separate daemon thread (retrieved via an ExecutorService) reads from the provided InputStream and places the datagrams into a datagram queue until the datagram queue's capacity is reached. If the queue is empty, then the AbstractDatagramsReceiver.receive() ( AbstractDatagramsReceiver.receiveAll()) method is blocked until the daemon thread places new datagrams into the queue. See also AbstractDatagramsReceiver.

Constructor Details

AbstractPrefetchInputStreamReceiver

public AbstractPrefetchInputStreamReceiver()

Creates an AbstractPrefetchInputStreamReceiver.

AbstractPrefetchInputStreamReceiver

public AbstractPrefetchInputStreamReceiver(ExecutorService aExecutorService)

Creates an AbstractPrefetchInputStreamReceiver using the given ExecutorService required for thread generation in an JEE environment.

Parameters:

aExecutorService - The ExecutorService to be used, when null then an ExecutorService something line Executors.newCachedThreadPool() is then retrieved.

AbstractPrefetchInputStreamReceiver

public AbstractPrefetchInputStreamReceiver(int aQueueCapacity)

Creates an AbstractPrefetchInputStreamReceiver using the given datagram queue capacity.

Parameters:

aQueueCapacity - The capacity of the prefetch queue before it blocks until data is read via AbstractDatagramsReceiver.receive() ( AbstractDatagramsReceiver.receiveAll()).

AbstractPrefetchInputStreamReceiver

public AbstractPrefetchInputStreamReceiver(int aQueueCapacity,
 ExecutorService aExecutorService)

Creates an AbstractPrefetchInputStreamReceiver using the given ExecutorService required for thread generation in an JEE environment.

Parameters:

aQueueCapacity - The capacity of the prefetch queue before it blocks until data is read via AbstractDatagramsReceiver.receive() ( AbstractDatagramsReceiver.receiveAll()).

aExecutorService - The ExecutorService to be used, when null then an ExecutorService something line Executors.newCachedThreadPool() is then retrieved.
