    • handle

      public void handle(Limit limit) throws InterruptedException
      Description copied from interface: ServerConnection
      Start handling the connection. Data is provided through ServerConnectionSelector.connection(io.helidon.webserver.ConnectionContext).
      Specified by:
      handle in interface ServerConnection
      Parameters:
      limit - that is responsible for maximal concurrent request limit, the connection implementation is responsible invoking each request within the limit's LimitAlgorithm.invoke(java.util.concurrent.Callable)
      Throws:
      InterruptedException - to interrupt any waiting state and terminate this connection

    • handle

      public void handle(Semaphore requestSemaphore) throws InterruptedException
      Description copied from interface: ServerConnection
      Start handling the connection. Data is provided through ServerConnectionSelector.connection(io.helidon.webserver.ConnectionContext).
      Specified by:
      handle in interface ServerConnection
      Parameters:
      requestSemaphore - semaphore that is responsible for maximal concurrent request limit, the connection implementation is responsible for acquiring a permit from the semaphore for the duration of a request, and releasing it when the request ends; please be very careful, as this may lead to complete stop of the server if incorrectly implemented
      Throws:
      InterruptedException - to interrupt any waiting state and terminate this connection
