Interface SessionRequest

  • All Known Implementing Classes:
    SessionRequestImpl
    public interface SessionRequest
    SessionRequest interface represents a request to establish a new connection (or session) to a remote host. It can be used to monitor the status of the request, to block waiting for its completion, or to cancel the request.

    Implementations of this interface are expected to be threading safe.

    Since:
    4.0

    • Method Detail

      • getRemoteAddress

        java.net.SocketAddress getRemoteAddress()
        Returns socket address of the remote host.
        Returns:
        socket address of the remote host

      • getLocalAddress

        java.net.SocketAddress getLocalAddress()
        Returns local socket address.
        Returns:
        local socket address.

      • getAttachment

        java.lang.Object getAttachment()
        Returns attachment object will be added to the session's context upon initialization. This object can be used to pass an initial processing state to the protocol handler.
        Returns:
        attachment object.

      • isCompleted

        boolean isCompleted()
        Determines whether the request has been completed (either successfully or unsuccessfully).
        Returns:
        true if the request has been completed, false if still pending.

      • getSession

        IOSession getSession()
        Returns IOSession instance created as a result of this request or null if the request is still pending.
        Returns:
        I/O session or null if the request is still pending.

      • getException

        java.io.IOException getException()
        Returns IOException instance if the request could not be successfully executed due to an I/O error or null if no error occurred to this point.
        Returns:
        I/O exception or null if no error occurred to this point.

      • waitFor

        void waitFor()
      throws java.lang.InterruptedException
        Waits for completion of this session request.
        Throws:
        java.lang.InterruptedException - in case the execution process was interrupted.

      • setConnectTimeout

        void setConnectTimeout​(int timeout)
        Sets connect timeout value in milliseconds.
        Parameters:
        timeout - connect timeout value in milliseconds.

      • getConnectTimeout

        int getConnectTimeout()
        Returns connect timeout value in milliseconds.
        Returns:
        connect timeout value in milliseconds.

      • cancel

        void cancel()
        Cancels the request. Invocation of this method will set the status of the request to completed and will unblock threads blocked in the {waitFor()} method.
