Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface ShortBlockProvider

The ShortBlockProvider is used to receive short blocks (arrays) in a unified way. The readDatagrams() method provides the next available short block from the counterpart BlockSender or DatagramSender; in case there is none available, then this method halts until one is available.

Method Summary

Modifier and Type	Method	Description
default short[]	readDatagrams()	Reads (receives) the next short block passed from a BlockSender or DatagramSender counterpart.
short[]	readDatagrams(int aBlockSize)	Similar to readDatagrams() though at maximum the amount of data as provided by the block-size is returned.

Method Detail

readDatagrams

default short[] readDatagrams()
                       throws org.refcodes.component.OpenException,
                              java.lang.InterruptedException

Reads (receives) the next short block passed from a BlockSender or DatagramSender counterpart. In case none short block is available, then this method blocks until one is available. When a Thread is waiting for a short to be read and Thread.interrupt() is being called, then the operation is aborted and an InterruptedException is thrown.

Returns:

The next short block sent from the BlockSender or DatagramReceiver counterpart.

Throws:

org.refcodes.component.OpenException - Thrown in case opening or accessing an open line (connection, junction, link) caused problems.

java.lang.InterruptedException - Thrown when a Thread is waiting, sleeping, or otherwise occupied, and the Thread is interrupted, either before or during the activity.

readDatagrams

short[] readDatagrams(int aBlockSize)
               throws org.refcodes.component.OpenException,
                      java.lang.InterruptedException

Similar to readDatagrams() though at maximum the amount of data as provided by the block-size is returned.

Parameters:

aBlockSize - The block-size which is not to exceeded by the returned data. A value of -1 specifies to retrieve all available datagrams (same behavior as method readDatagrams().

Returns:

The next short block sent from the BlockSender or DatagramReceiver counterpart.

Throws:

org.refcodes.component.OpenException - Thrown in case opening or accessing an open line (connection, junction, link) caused problems.

java.lang.InterruptedException - Thrown when a Thread is waiting, sleeping, or otherwise occupied, and the Thread is interrupted, either before or during the activity.
