public interface InvokeHandler
This interface provides a dispatching mechanism for an incoming call. It is invoked by the ORB to dispatch a request to a servant.

  • Method Details

    • _invoke

      OutputStream _invoke(String method, InputStream input, ResponseHandler handler) throws SystemException
      Invoked by the ORB to dispatch a request to the servant. ORB passes the method name, an InputStream containing the marshalled arguments, and a ResponseHandler which the servant uses to construct a proper reply. Only CORBA SystemException may be thrown by this method. The method must return an OutputStream created by the ResponseHandler which contains the marshalled reply. A servant must not retain a reference to the ResponseHandler beyond the lifetime of a method invocation. Servant behaviour is defined as follows:

      1. Determine correct method, and unmarshal parameters from InputStream.

      2. Invoke method implementation.

      3. If no user exception, create a normal reply using ResponseHandler.

      4. If user exception occurred, create exception reply using ResponseHandler.

      5. Marshal reply into OutputStream returned by ResponseHandler.

      6. Return OutputStream to ORB.

      Parameters:
      method - The method name.
      input - The InputStream containing the marshalled arguments.
      handler - The ResponseHandler which the servant uses to construct a proper reply
      Returns:
      The OutputStream created by the ResponseHandler which contains the marshalled reply
      Throws:
      SystemException - is thrown when invocation fails due to a CORBA system exception.
      SystemException
