public interface SuspendableReadChannel extends CloseableChannel
A suspendable readable channel. This type of channel is associated with a listener which can suspend and resume reads as needed.
  • Method Details

    • suspendReads

      void suspendReads()
      Suspend further read notifications on this channel.
    • resumeReads

      void resumeReads()
      Resume reads on this channel. The read listener will be called as soon as there is data available to be read.
    • isReadResumed

      boolean isReadResumed()
      Determine whether reads are resumed.
      Returns:
      true if reads are resumed, false if reads are suspended
    • wakeupReads

      @Deprecated void wakeupReads()
      Deprecated.
      Users should instead submit Runnable tasks to the channel thread when this functionality is needed.
      Resume reads on this channel, and force the read listener to be triggered even if the channel isn't actually readable.
    • shutdownReads

      void shutdownReads() throws IOException
      Places this readable channel at "end of stream". Further reads will result in EOF. Shutting down all directions of a channel will cause CloseableChannel.close() to be called automatically.
      Throws:
      IOException - if an I/O error occurs
    • awaitReadable

      void awaitReadable() throws IOException
      Block until this channel becomes readable again. This method may return spuriously before the channel becomes readable.
      Throws:
      InterruptedIOException - if the operation is interrupted; the thread's interrupt flag will be set as well
      IOException - if an I/O error occurs
      Since:
      1.2
    • awaitReadable

      void awaitReadable(long time, TimeUnit timeUnit) throws IOException
      Block until this channel becomes readable again, or until the timeout expires. This method may return spuriously before the channel becomes readable or the timeout expires.
      Parameters:
      time - the time to wait
      timeUnit - the time unit
      Throws:
      InterruptedIOException - if the operation is interrupted; the thread's interrupt flag will be set as well
      IOException - if an I/O error occurs
      Since:
      1.2
    • getReadThread

      @Deprecated XnioExecutor getReadThread()
      Deprecated.
      The CloseableChannel.getIoThread() method should be used instead.
      Get the read thread for this channel.
      Returns:
      the thread, or null if none is configured or available
    • getReadSetter

      Get the setter which can be used to change the read listener for this channel.
      Returns:
      the setter
      Since:
      2.0
    • getCloseSetter

      ChannelListener.Setter<? extends SuspendableReadChannel> getCloseSetter()
      Get the setter which can be used to change the close listener for this channel. If the channel is already closed, then the listener will not be called.
      Specified by:
      getCloseSetter in interface CloseableChannel
      Returns:
      the setter
