Constructor	Description
AbstractBytesReceiver()	Constructs a AbstractBytesReceiver with a default sized blocking queue enabling a maximum of AbstractBytesDestination.DATAGRAM_QUEUE_SIZE datagrams. ------------------------------------------------------------------------- Make sure your code fetches the datagrams quick enough to prevent filling up of the queue.
AbstractBytesReceiver(int aCapacity)	Constructs a AbstractBytesReceiver with a custom sized blocking queue enabling a maximum of datagrams as specified by the capacity parameter. ------------------------------------------------------------------------- Make sure your code fetches the datagrams quick enough to prevent filling up of the queue.

Constructor Detail

AbstractBytesReceiver

public AbstractBytesReceiver()

Constructs a AbstractBytesReceiver with a default sized blocking queue enabling a maximum of AbstractBytesDestination.DATAGRAM_QUEUE_SIZE datagrams. ------------------------------------------------------------------------- Make sure your code fetches the datagrams quick enough to prevent filling up of the queue. In case the queue is filled up, adding elements via AbstractBytesDestination.pushDatagram(byte) to the queue is blocked until elements are taken from the queue via receiveByte().

AbstractBytesReceiver

public AbstractBytesReceiver(int aCapacity)

Constructs a AbstractBytesReceiver with a custom sized blocking queue enabling a maximum of datagrams as specified by the capacity parameter. ------------------------------------------------------------------------- Make sure your code fetches the datagrams quick enough to prevent filling up of the queue. In case the queue is filled up, adding elements via AbstractBytesDestination.pushDatagram(byte) to the queue is blocked until elements are taken from the queue via receiveByte().

Parameters:

aCapacity - The capacity of the queue holding the received datagrams.

Method Detail

receiveByte

public byte receiveByte()
                 throws IOException,
                        EOFException

Reads (receives) the next byte, in case none byte is available, then this method blocks until one is available.

Specified by:

receiveByte in interface ByteDestination

Specified by:

receiveByte in interface BytesDestination

Overrides:

receiveByte in class AbstractBytesDestination

Returns:

The next byte available .

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.

receiveAllBytes

public byte[] receiveAllBytes()
                       throws IOException,
                              EOFException

Reads (receives) the all currently available data.

Specified by:

receiveAllBytes in interface BytesDestination

Specified by:

receiveAllBytes in interface BytesReceiver

Overrides:

receiveAllBytes in class AbstractBytesDestination

Returns:

The according data.

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.

receiveBytes

public byte[] receiveBytes(int aMaxLength)
                    throws IOException,
                           EOFException

Similar to BytesDestination.receiveAllBytes() though at maximum the amount of data as of the provided length returned.

Specified by:

receiveBytes in interface BytesDestination

Specified by:

receiveBytes in interface BytesReceiver

Overrides:

receiveBytes in class AbstractBytesDestination

Parameters:

aMaxLength - 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 BytesDestination.receiveAllBytes().

Returns:

The according data.

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.

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

Specified by:

available in interface Skippable

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.

close

public void close()
