ClientRequestInfoOperations

public interface ClientRequestInfoOperations implements org.omg.PortableInterceptor.RequestInfoOperations

Request Information, accessible to client-side request interceptors.

Some attributes and operations on ClientRequestInfo are not valid at all interception points. The following table shows the validity of each attribute or operation. If it is not valid, attempting to access it will result in a BAD_INV_ORDER being thrown with a standard minor code of 14.

send_request send_poll receive_reply receive_exception receive_other

Inherited from RequestInfo:

request_id
yes yes yes yes yes

operation
yes yes yes yes yes

arguments
yes₁ no yes no no

exceptions
yes no yes yes yes

contexts
yes no yes yes yes

operation_context
yes no yes yes yes

result
no no yes no no

response_expected
yes yes yes yes yes

sync_scope
yes no yes yes yes

reply_status
no no yes yes yes

forward_reference
no no no no yes₂

get_slot
yes yes yes yes yes

get_request_service_context
yes no yes yes yes

get_reply_service_context
no no yes yes yes

ClientRequestInfo-specific:

target
yes yes yes yes yes

effective_target
yes yes yes yes yes

effective_profile
yes yes yes yes yes

received_exception
no no no yes no

received_exception_id
no no no yes no

get_effective_component
yes no yes yes yes

get_effective_components
yes no yes yes yes

get_request_policy
yes no yes yes yes

add_request_service_context
yes no no no no

When ClientRequestInfo is passed to send_request, there is an entry in the list for every argument, whether in, inout, or out. But only the in and inout arguments will be available.
If the reply_status atribute is not LOCATION_FORWARD, accessing this attribute will throw BAD_INV_ORDER with a standard minor code of 14.

Fields Summary
Constructors Summary
Methods Summary
public void add_request_service_context(org.omg.IOP.ServiceContext service_context, boolean replace)
Allows Interceptors to add service contexts to the request.
There is no declaration of the order of the service contexts. They may or may not appear in the order that they are added.
param
service_context The IOP.ServiceContext to be added to the request.
param
replace Indicates the behavior of this operation when a service context already exists with the given ID. If false, then BAD_INV_ORDER with a standard minor code of 15 is thrown. If true, then the existing service context is replaced by the new one.
public org.omg.IOP.TaggedProfile effective_profile()
Returns the profile that will be used to send the request. If a location forward has occurred for this operation's object and that object's profile changed accordingly, then this profile will be that located profile.
public org.omg.CORBA.Object effective_target()
Returns the actual object on which the operation will be invoked. If the reply_status is LOCATION_FORWARD, then on subsequent requests, effective_target will contain the forwarded IOR while target will remain unchanged.

#target
public org.omg.IOP.TaggedComponent get_effective_component(int id)
Returns the IOP.TaggedComponent with the given ID from the profile selected for this request.
If there is more than one component for a given component ID, it is undefined which component this operation returns. If there is more than one component for a given component ID, get_effective_components should be called instead.
param
id The component id of the component which is to be returned.
return
The IOP.TaggedComponent obtained with the given identifier.
exception
BAD_PARAM thrown, with a standard minor code of 28, if no component exists for the given component ID.
see
#get_effective_components
public org.omg.IOP.TaggedComponent[] get_effective_components(int id)
Returns an array of all tagged components with the given ID from the profile selected for this request.
param
id The component id of the components which are to be returned.
return
An array of TaggedComponent objects, each of which contains the given identifier.
exception
BAD_PARAM thrown, with a standard minor code of 28, if no component exists for the given component ID.
see
#get_effective_component
public org.omg.CORBA.Policy get_request_policy(int type)
Returns the given policy in effect for this operation.
exception
INV_POLICY thrown, with a standard minor code of 1, if the policy type is not valid either because the specified type is not supported by this ORB or because a policy object of that type is not associated with this Object
param
type The policy type which specifies the policy to be returned.
return
The CORBA.Policy obtained with the given type.

PortableInterceptor package comments for limitations / unimplemented features
public org.omg.CORBA.Any received_exception()
Returns an any which contains the exception to be returned to the client.
If the exception is a user exception which cannot be inserted into an any (e.g., it is unknown or the bindings don t provide the TypeCode), then this attribute will be an any containing the system exception UNKNOWN with a standard minor code of 1. However, the repository id of the exception is available in the received_exception_id attribute.
see
#received_exception_id
public java.lang.String received_exception_id()
Returns the repository id of the exception to be returned to the client.

public org.omg.CORBA.Object target()
Returns the object which the client called to perform the operation.
