  • Method Details

    • shutdownInput

      protected final void shutdownInput()

    • shutdownOutput

      public final void shutdownOutput()
      Description copied from interface: EndPoint
      Shutdown the output.

      This call indicates that no more data will be sent on this endpoint that that the remote end should read an EOF once all previously sent data has been consumed. Shutdown may be done either at the TCP/IP level, as a protocol exchange (Eg TLS close handshake) or both.

      If the endpoint has EndPoint.isInputShutdown() true, then this call has the same effect as EndPoint.close().

      Specified by:
      shutdownOutput in interface EndPoint

    • close

      public final void close()
      Description copied from interface: EndPoint
      Close any backing stream associated with the endpoint
      Specified by:
      close in interface AutoCloseable
      Specified by:
      close in interface Closeable
      Specified by:
      close in interface EndPoint

    • close

      protected final void close(Throwable failure)

    • doShutdownInput

      protected void doShutdownInput()

    • doShutdownOutput

      protected void doShutdownOutput()

    • doClose

      protected void doClose()

    • onClose

    • isOutputShutdown

      public boolean isOutputShutdown()
      Description copied from interface: EndPoint
      Test if output is shutdown. The output is shutdown by a call to EndPoint.shutdownOutput() or EndPoint.close().
      Specified by:
      isOutputShutdown in interface EndPoint
      Returns:
      true if the output is shutdown or the endpoint is closed.

    • isInputShutdown

      public boolean isInputShutdown()
      Description copied from interface: EndPoint
      Test if the input is shutdown. The input is shutdown if an EOF has been read while doing a EndPoint.fill(ByteBuffer). Once the input is shutdown, all calls to EndPoint.fill(ByteBuffer) will return -1, until such time as the end point is close, when they will return EofException.
      Specified by:
      isInputShutdown in interface EndPoint
      Returns:
      True if the input is shutdown or the endpoint is closed.

    • fillInterested

      public void fillInterested(Callback callback)
      Description copied from interface: EndPoint

      Requests callback methods to be invoked when a call to EndPoint.fill(ByteBuffer) would return data or EOF.

      Specified by:
      fillInterested in interface EndPoint
      Parameters:
      callback - the callback to call when an error occurs or we are readable. The callback may implement the Invocable interface to self declare its blocking status. Non-blocking callbacks may be called more efficiently without dispatch delays.

      Description copied from interface: EndPoint

      Requests callback methods to be invoked when a call to EndPoint.fill(ByteBuffer) would return data or EOF.

      tryFillInterested in interface EndPoint
      Parameters:
      callback - the callback to call when an error occurs or we are readable. The callback may implement the Invocable interface to self declare its blocking status. Non-blocking callbacks may be called more efficiently without dispatch delays.
      Returns:
      true if set

    • isFillInterested

    • write

      public void write(Callback callback, ByteBuffer... buffers) throws IllegalStateException
      Description copied from interface: EndPoint

      Writes the given buffers via EndPoint.flush(ByteBuffer...) and invokes callback methods when either all the data has been flushed or an error occurs.

      Specified by:
      write in interface EndPoint
      Parameters:
      callback - the callback to call when an error occurs or the write completed. The callback may implement the Invocable interface to self declare its blocking status. Non-blocking callbacks may be called more efficiently without dispatch delays.
      buffers - one or more ByteBuffers that will be flushed.
      Throws:
      WritePendingException - if another write operation is concurrent.
      IllegalStateException

    • upgrade

      public void upgrade(Connection newConnection)
      Description copied from interface: EndPoint

      Upgrades this EndPoint from the current connection to the given new connection.

      Closes the current connection, links this EndPoint to the new connection and then opens the new connection.

      If the current connection is an instance of Connection.UpgradeFrom then a buffer of unconsumed bytes is requested. If the buffer of unconsumed bytes is non-null and non-empty, then the new connection is tested: if it is an instance of Connection.UpgradeTo, then the unconsumed buffer is passed to the new connection; otherwise, an exception is thrown since there are unconsumed bytes that cannot be consumed by the new connection.

      Specified by:
      upgrade in interface EndPoint
      Parameters:
      newConnection - the connection to upgrade to
