        public PrefetchInputStreamByteReceiverImpl​(java.io.InputStream aInputStream)
                                            throws org.refcodes.component.OpenException
        Instantiates a new prefetch input stream byte receiver impl.
        Parameters:
        aInputStream - the input stream
        Throws:
        org.refcodes.component.OpenException - the open exception

      • 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 byte[] readDatagrams​()
                             throws org.refcodes.component.OpenException,
                                    java.lang.InterruptedException
        Caution: Reads till an OpenException (or an InterruptedException in case of blocking till more data is available) occurs. Reads (receives) the next byte block passed from a BlockSender or DatagramSender counterpart. In case none byte block is available, then this method blocks until one is available. When a Thread is waiting for a byte to be read and Thread.interrupt() is being called, then the operation is aborted and an InterruptedException is thrown.
        Specified by:
        readDatagrams in interface ByteBlockProvider
        Specified by:
        readDatagrams in interface ByteProvider
        Specified by:
        readDatagrams in interface ByteReceiver
        Returns:
        The next byte 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.
      • 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 byte readDatagram​()
                          throws org.refcodes.component.OpenException,
                                 java.lang.InterruptedException
        Reads (receives) the next byte passed from a DatagramSender counterpart. In case none byte is available, then this method blocks until one is available. To prevent blocking, use the ByteDatagramReceiver 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 byte to be read and Thread.interrupt() is being called, then the operation is aborted and an InterruptedException is thrown.
        Specified by:
        readDatagram in interface ByteDatagramProvider
        Returns:
        The next byte sent from the ByteDatagramSender 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.
      • isClosable

        public boolean isClosable​()
        Specified by:
