Constructor Detail

InputStreamReceiver

public InputStreamReceiver(InputStream aInputStream)
                    throws IOException

Instantiates a new input stream receiver impl.

Parameters:

aInputStream - the input stream

Throws:

IOException - the open exception

Method Detail

isClosed

public boolean isClosed()

Specified by:

isClosed in interface org.refcodes.component.ClosedAccessor

isOpened

public boolean isOpened()

Specified by:

isOpened in interface org.refcodes.component.ConnectionStatusAccessor

Specified by:

isOpened in interface org.refcodes.component.OpenedAccessor

available

public int available()
              throws IOException

Determines the number of available datagram from a DatagramTransmitter. Use the DatagramDestination extenison's DatagramDestination.receive() method for retrieving available datagrams.

Specified by:

available in interface Availability

Returns:

The number of datagrams ready to be retrieved .

Throws:

IOException - Thrown in case opening or accessing an open line (connection, junction, link) caused problems.

receiveAll

public DATA[] receiveAll()
                  throws IOException

Reads (receives) the all currently available data.

Specified by:

receiveAll in interface DatagramsDestination<DATA extends Serializable>

Specified by:

receiveAll in interface DatagramsReceiver<DATA extends Serializable>

Returns:

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

Throws:

IOException - Thrown in case opening or accessing an open line (connection, junction, link) caused problems.

EOFException - Signals that an end of file or end of stream has been reached unexpectedly during input.

getConnectionStatus

public org.refcodes.component.ConnectionStatus getConnectionStatus()

Specified by:

getConnectionStatus in interface org.refcodes.component.ConnectionStatusAccessor

close

public void close()
           throws IOException

Specified by:

close in interface org.refcodes.component.Closable

Throws:

IOException

receive

public DATA receive()
             throws IOException

Reads (receives) the next datagram passed from a DatagramTransmitter counterpart. In case none datagram is available, then this method blocks until one is available. To prevent blocking, use the DatagramReceiver extension's Availability.available() method to test beforehand whether a byte is available (in a multi-threaded usage scenario, Availability.available() is not a reliable indicator whether this method will block or not). When a Thread is waiting for a datagram to be read and Thread.interrupt() is being called, then the operation is aborted and an InterruptedException is thrown.

Specified by:

receive in interface DatagramDestination<DATA extends Serializable>

Specified by:

receive in interface DatagramsDestination<DATA extends Serializable>

Returns:

The next datagram sent from the DatagramTransmitter counterpart.

Throws:

IOException - Thrown in case opening or accessing an open line (connection, junction, link) caused problems.

EOFException - Signals that an end of file or end of stream has been reached unexpectedly during input.

isClosable

public boolean isClosable()

Specified by:

isClosable in interface org.refcodes.component.Closable.CloseAutomaton
