Class AbstractInputStreamReceiver<DATA extends Serializable>

java.lang.Object
org.refcodes.component.AbstractConnectableAutomaton
org.refcodes.io.AbstractInputStreamReceiver<DATA>
Type Parameters:
DATA - The type of the datagram to be operated with.
All Implemented Interfaces:
org.refcodes.component.Closable, org.refcodes.component.Closable.CloseAutomaton, org.refcodes.component.ClosedAccessor, org.refcodes.component.ConnectableComponent, org.refcodes.component.ConnectableComponent.ConnectableAutomaton, org.refcodes.component.ConnectionStatusAccessor, org.refcodes.component.OpenedAccessor, Availability, DatagramDestination<DATA>, DatagramReceiver<DATA>, DatagramsDestination<DATA>, DatagramsReceiver<DATA>, Receivable

public abstract class AbstractInputStreamReceiver<DATA extends Serializable> extends org.refcodes.component.AbstractConnectableAutomaton implements DatagramsReceiver<DATA>
Abstract implementation of the DatagramsReceiver interface. The open(InputStream), AbstractConnectableAutomaton.setConnectionStatus(ConnectionStatus) and AbstractConnectableAutomaton.isOpenable() methods are your hooks when extending this class.

      public AbstractInputStreamReceiver()

  • Method Details

    • available

      public int available() throws IOException
      Checks for datagram.
      Specified by:
      available in interface Availability
      Returns:
      true, if successful
      Throws:
      IOException - the open exception

    • 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.

    • close

      public void close() throws IOException
      Specified by:
      close in interface org.refcodes.component.Closable
      Overrides:
      close in class org.refcodes.component.AbstractConnectableAutomaton
      Throws:
      IOException

    • open

      protected void open(InputStream aInputStream) throws IOException
      Open, see also ConnectionOpenable.open(Object).
      Parameters:
      aInputStream - the input stream
      Throws:
      IOException - the open exception

    • isOpenable

      protected boolean isOpenable(InputStream aInputStream)
      Checks if is openable. See also ConnectionOpenable.ConnectionOpenAutomaton.isOpenable(Object).
      Parameters:
      aInputStream - the input stream
      Returns:
      true, if is openable
