public interface ServerRequestInfoOperations
Request Information, accessible to server-side request interceptors.
Some attributes and operations on ServerRequestInfo
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.

Any sending_exception()
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.

CORBA.Policy
object shall
only be a policy whose type was registered via
register_policy_factory
.
type
- The CORBA.PolicyType
which specifies the
policy to be returned.
CORBA.Policy
obtained with the given
policy type.
INV_POLICY
- thrown, with a standard minor code of 2, if
a policy for the given type was not registered via
register_policy_factory

void set_slot(int id, Any data) throws InvalidSlot
PortableInterceptor.Current
that is in the scope of
the request. If data already exists in that slot, it will be
overwritten.
id
- The id of the slot.data
- The data, in the form of an any, to store in that slot.
InvalidSlot
- thrown if the ID does not define an allocated
slot.Current
boolean target_is_a(String id)
id
- The caller wants to know if the servant is this
repository id.
void add_reply_service_context(ServiceContext service_context, boolean replace)
There is no declaration of the order of the service contexts. They may or may not appear in the order that they are added.
service_context
- The IOP.ServiceContext
to add to
the reply.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.
BAD_INV_ORDER
- thrown, with a standard minor code of 15, if
replace is false and a service context already exists with the
given ID.
