    • 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.OpenedAccessor

      • hasDatagram

        public boolean hasDatagram​()
                    throws org.refcodes.component.OpenException
        Determines whether a datagram is available from a DatagramSender. Use the DatagramProvider extenison's DatagramProvider.readDatagram() method for retrieving the available datagram.
        Specified by:
        hasDatagram in interface Receivable
        Returns:
        True in case there is a datagram ready to be retrieved .
        Throws:
        org.refcodes.component.OpenException - Thrown in case opening or accessing an open line (connection, junction, link) caused problems.

      • readDatagrams

        public DATA[] readDatagrams​()
                     throws org.refcodes.component.OpenException,
                            java.lang.InterruptedException
        Read datagrams.
        Specified by:
        readDatagrams in interface BlockProvider<DATA extends java.io.Serializable>
        Specified by:
        readDatagrams in interface Provider<DATA extends java.io.Serializable>
        Specified by:
        readDatagrams in interface Receiver<DATA extends java.io.Serializable>
        Returns:
        the DAT a[]
        Throws:
        org.refcodes.component.OpenException - the open exception
        java.lang.InterruptedException - the interrupted exception

      • getConnectionStatus

        public org.refcodes.component.ConnectionStatus getConnectionStatus​()
        Specified by:
        getConnectionStatus in interface org.refcodes.component.ConnectionStatusAccessor

      • releaseAll

        public void releaseAll​()
        Specified by:
        releaseAll in interface org.refcodes.mixin.Releaseable

      • close

        public void close​()
           throws org.refcodes.component.CloseException
        Specified by:
        close in interface org.refcodes.component.Closable
        Throws:
        org.refcodes.component.CloseException

      • readDatagram

        public DATA readDatagram​()
                  throws org.refcodes.component.OpenException,
                         java.lang.InterruptedException
        Reads (receives) the next datagram passed from a DatagramSender counterpart. In case none datagram is available, then this method blocks until one is available. To prevent blocking, use the DatagramReceiver extension's Receivable.hasDatagram() method to test beforehand whether a byte is available (in a multi-threaded usage scenario, Receivable.hasDatagram() 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:
        readDatagram in interface DatagramProvider<DATA extends java.io.Serializable>
        Returns:
        The next datagram sent from the DatagramSender 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.
