ServerRequestInfoOperations

public interface ServerRequestInfoOperations implements org.omg.PortableInterceptor.RequestInfoOperations
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.

add_reply_service_context yes yes yes yes yes

  1. When ServerRequestInfo is passed to receive_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.
  2. If the reply_status attribute is not LOCATION_FORWARD, accessing this attribute will throw BAD_INV_ORDER with a standard minor code of 14.
  3. If the servant locator caused a location forward, or thrown an exception, this attribute/operation may not be available in this interception point. NO_RESOURCES with a standard minor code of 1 will be thrown if it is not available.
  4. The operation is not available in this interception point because the necessary information requires access to the target object's servant, which may no longer be available to the ORB. For example, if the object's adapter is a POA that uses a ServantLocator, then the ORB invokes the interception point after it calls ServantLocator.postinvoke()

Fields Summary
Constructors Summary
Methods Summary
public byte[]adapter_id()
Returns the opaque identifier for the object adapter.

public java.lang.String[]adapter_name()
Returns the sequence of strings that identifies the object adapter instance that is handling this request.

public voidadd_reply_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 add to the reply.
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.
exception
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.

public org.omg.CORBA.Policyget_server_policy(int type)
Returns the policy in effect for this operation for the given policy type. The returned CORBA.Policy object shall only be a policy whose type was registered via register_policy_factory.

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

ORBInitInfo#register_policy_factory

public byte[]object_id()
Returns the opaque object_id describing the target of the operation invocation.

public java.lang.Stringorb_id()
Returns the ID that was used to create the ORB.

public org.omg.CORBA.Anysending_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.

PortableInterceptor package comments for limitations / unimplemented features

public java.lang.Stringserver_id()
Returns the server ID that was specified on ORB::init using the -ORBServerId argument.

public voidset_slot(int id, org.omg.CORBA.Any data)
Allows an Interceptor to set a slot in the PortableInterceptor.Current that is in the scope of the request. If data already exists in that slot, it will be overwritten.

param
id The id of the slot.
param
data The data, in the form of an any, to store in that slot.
exception
InvalidSlot thrown if the ID does not define an allocated slot.

Current

public booleantarget_is_a(java.lang.String id)
Returns true if the servant is the given repository id, false if it is not.

param
id The caller wants to know if the servant is this repository id.
return
Is the servant the given RepositoryId?

public java.lang.Stringtarget_most_derived_interface()
Returns the repository id for the most derived interface of the servant.
