Invocation_Base (const Invocation_Base &) | |
Invocation_Base & | operator= (const Invocation_Base &) |
The base class for the invocation object.
This class is the base of the invocation object hierarchy. This hierarchy is classified based on the type of invocation and the mode of invocation. One of the objects from the hierarchy is created on the stack for every invocation.
In addition this class encapsulates the essential details that are required for PortableInterceptors to function correctly. Further this class also provides some helper and accessor methods that are used by clients.

otarget | The original target on which this invocation was started. |
target | the target on which this invocation is flowing ie. the effective target |
op | operation details of the invocation on target |
response_expected | flag to indicate whether the operation encapsulated by op returns a response or not. |

CORBA::Exception* TAO::Invocation_Base::caught_exception | ( | void | ) |
The client requestor adapter.
CORBA::Object_ptr TAO::Invocation_Base::effective_target | ( | void | ) | const |
Return the effective target of the invocation.
Please see the PortableInterceptor specification in the CORBA spec to understand what effective target means.
CORBA::Object_ptr TAO::Invocation_Base::forwarded_reference | ( | void | ) |
Accessor and mutator methods for forwarded object locations. These access methods have to be public so that the PortableInterceptor can use them
void TAO::Invocation_Base::forwarded_reference | ( | CORBA::Object_ptr | o | ) |
Accessor and mutator methods.
|
protected |
The client requestor adapter.
|
protected |
Helper methods to handle interception calls when exceptions are thrown by the PortableInterceptor.
TAO::Invocation_Status TAO::Invocation_Base::invoke_status | ( | void | ) | const |
Invocation status.
void TAO::Invocation_Base::invoke_status | ( | Invocation_Status | s | ) |
Mutator to set the invocation status.
bool TAO::Invocation_Base::is_remote_request | ( | ) | const |
Accessor used to determine if the current invocation is part of a remote request, and if not, it will be considered to be part of a collocated request.
TAO_Operation_Details & TAO::Invocation_Base::operation_details | ( | void | ) |
The operaton details of the invocation.
|
private |
PortableInterceptor::ReplyStatus TAO::Invocation_Base::pi_reply_status | ( | void | ) | const |
The client requestor adapter.
|
protected |
Helper method to invoke receive_other interception call to all the registered interceptors.
|
protected |
Helper method to invoke receive_reply interception call to all the registered interceptors.
TAO_Service_Context & TAO::Invocation_Base::reply_service_context | ( | void | ) |
Accessor and mutator methods.
GIOP::ReplyStatusType TAO::Invocation_Base::reply_status | ( | void | ) | const |
Accessor of reply_status of the invocation.
void TAO::Invocation_Base::reply_status | ( | GIOP::ReplyStatusType | s | ) |
Mutator of reply_status of the invocation.
TAO_Service_Context & TAO::Invocation_Base::request_service_context | ( | void | ) |
Accessors for the service context list.
The service context lists are actually cached elsewhere. Providing this accessor helps the PI to access this list in both remote and collocated mode.
CORBA::Boolean TAO::Invocation_Base::response_expected | ( | void | ) | const |
Does this invocation return a response?
|
protected |
Helper method to invoke send_request interception call to all the registered interceptors.
size_t& TAO::Invocation_Base::stack_size | ( | void | ) |
Operations invoked by the PortableInterceptor::ClientRequestInfo object to get details about the operation and related stuff. Return a reference to the number of interceptors pushed on to the current interceptor flow stack.
CORBA::Object_ptr TAO::Invocation_Base::steal_forwarded_reference | ( | void | ) |
Return the forwarded object location by loosing ownership.
TAO_Stub * TAO::Invocation_Base::stub | ( | void | ) | const |
Accessor and mutator methods.
CORBA::Object_ptr TAO::Invocation_Base::target | ( | void | ) | const |
Return the target object.
|
private |
Pointer to the caught exception.
|
protected |
The client requestor adapter.
|
protected |
The operation details on which we are operating on.
void TAO::Invocation_Base::exception |
Change the exception status.
|
protected |
Forwarded object reference.
|
protected |
The client requestor adapter.
|
private |
Flag used to distinguish a remote invocation versus a collocated (thru-poa) invocation.
|
private |
The original target on which the invocation was started.
The following object reference pointers are not duplicated. They are cached for portable interceptors, and they just live for the lifetime of the request. Hence there is no point in duplicating the pointers.
|
protected |
A GIOP reply status of the invocation.
|
protected |
Is response expected?
|
protected |
The client requestor adapter.
|
protected |
The client requestor adapter.
|

|
private |
The effective target on which the invocation is on.
