public class LocalClientRequest
extends AbstractClientRequest

This is a very hacked version of the IIOPClientRequest to route calls inside the ORB. This is necessary because of some IDL compilers (as JDK1.4) that leave to the ORB all the local calls instead of handling them inside the stubs

Constructor Detail

### LocalClientRequest

    public LocalClientRequest(ORB orb,
                              int request_id,
                              Object target,
                              java.lang.String operation,
                              boolean response_expected,
                              Address[] adresses)

  Creates a new LocalClientRequest
  Parameters:
    `orb` - ORB
    `request_id` - the current request id
    `target` - target object for the request
    `operation` - operation
    `response_expected` - oneway call or not
    `adresses` - all the adresses of the target

Method Detail

### state

    public int state()

  Current request state.
  Returns:
    state

### is_request

    public boolean is_request()

  This returns true if this request is a standard request. While in the CREATED state it is valid to call any client request info operations which would be valid in the client side interception points send_request. The send_request interception points are called while in this state.

### is_locate

    public boolean is_locate()

  This returns true if this request is a locate request. Client side interceptors are not called for locate requests. ClientRequestInfo operations: arguments, exceptions, contexts, operation_context, result, get_request_service_context, get_reply_service_context, add_request_service_context are not valid. operation returns the empty string "", response_expected returns true. Note the extra value for reply_status, UNKNOWN_OBJECT.

### is_poll

    public boolean is_poll()

  Request is a poll. While in the CREATED state it is valid to call any client request info operations which would be valid in the client side interception points send_poll. The send_poll interception points are called while in this state.
  Returns:
    true if is a poll

### sync_scope

    public short sync_scope()

  returns the sync scope of the request (depends if it is one way or not)
  Returns:
    sync_scope

### response_expected

    public boolean response_expected()

  Description copied from interface: `RequestInfoOperations`
  Read accessor for response_expected attribute
  Following copied from interface: `org.omg.PortableInterceptor.RequestInfoOperations`
  Returns:
    the attribute value

### operation

    public java.lang.String operation()

  request operation
  Following copied from interface: `org.omg.PortableInterceptor.RequestInfoOperations`
  Returns:
    the attribute value

### cancel

    public boolean cancel(SystemException ex)

  Cancel the request with the specified system exception reply. This is valid in any state apart from COMPLETE. This may result in cancel messages being sent to the server. If this is successful state changes to COMPLETED/SYSTEM_EXCEPTION. If the provided exception's status is set to null the exception thown will set the exception status according to the request's state.
  Returns:
    true if the request is succesfully canceled.

### begin_marshal

    public OutputStream begin_marshal()

  Begin marshalling arguments. Valid in CREATED state. State changes to MARSHAL. If no arguments are required for marshalling this can enter the MARSHAL state and return null, this occours for locate requests and polls only. This may also return null if entering COMPLETE/SYSTEM_EXCEPTION/COMPLETED_NO, COMPLETE/LOCATION_FORWARD or COMPLETE/LOCATION_FORWARD_PERMINENT due to communication problems or client side interceptors.

### send_request

    public int send_request()

  When this returns the last fragment of the request has been sent. In MARSHAL state changes to WAITING or COMPLETE. This may result in entering COMPLETE/SYSTEM_EXCEPTION/COMPLETED_NO, COMPLETE/LOCATION_FORWARD or COMPLETE/LOCATION_FORWARD_PERMINENT due to communication problems.
  Returns:
    new state. May be WAITING or COMPLETE.

### poll_response

    public boolean poll_response()

  Poll to see if a response is available from the target. If in the WAITING state this will return true if wait_for_response would not have to wait for a response. In the UNMARSHAL and COMPLETE states this returns true, It is illegal to call this function in all other states.

### receive_response

    public InputStream receive_response()

  Get the response output stream. This function is valid in the UNMARSHAL state when reply_status is SUCESSFUL or USER_EXCEPTION. The returned input stream may throw a system exception with status COMPLETED_YES at any time. With the local server request no error can happen at this stage

### wait_for_response

    public int wait_for_response(long timeout)

  Wait for a response from the server. When this returns either the given wait_time has expired (WAITING), a response has arrived from the server (UNMARSHAL or COMPLETE), a transport error has occoured (COMPLETE), or for requests where no response is expected the sync scope is satisfied (COMPLETE). The request state will not exit the WAITING state unless this function is called.
  Parameters:
    `timeout` - Maximum amount of time to wait for response. <=0 to wait forever, > 0 for some timeout (in ms)
  Returns:
    new state. May be WAITING, UNMARSHAL or COMPLETE.

### reply_status

    public short reply_status()

  Returns the reply status of the request
  Returns:
    reply

### get_reply_service_context

    public ServiceContext get_reply_service_context(int id)

  Returns the service context of the request
  Parameters:
    `id` -
  Returns:
    The service context of the request.

### forward_reference

    public Object forward_reference()

  Return and eventually create a forward reference from a LOCATION_FORWARD reply.
  Returns:
    The forward reference in case one exists.

### forward_reference_ior

    public IOR forward_reference_ior()

  Get the ior associated with a forward reference. Calling this function instead of forward_reference avoids creating an enclosing delegate/object. This function is valid in the COMPLETE/LOCATION_FORWARD state.

### received_system_exception

    public SystemException received_system_exception()

  Get the system exception which would be contained in the any returned from receive_exception. This function is valid in the COMPLETE/SYSTEM_EXCEPTION state.

### received_exception

    public Any received_exception()

  returns the forward reference
  Following copied from interface: `org.omg.PortableInterceptor.ClientRequestInfoOperations`
  Returns:
    the attribute value

### received_exception_id

    public java.lang.String received_exception_id()

  returns the exception id if an exception has been sent by the server
  Following copied from interface: `org.omg.PortableInterceptor.ClientRequestInfoOperations`
  Returns:
    the attribute value
