Detailed Description

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.

Member Function Documentation

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.

TAO_Operation_Details & TAO::Invocation_Base::operation_details ( void  )

The operaton details of the invocation.

Invocation_Base& TAO::Invocation_Base::operator= ( const Invocation_Base ) [private]
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?

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.


Member Data Documentation

TAO_Operation_Details& TAO::Invocation_Base::details_ [protected]

The operation details on which we are operating on.

CORBA::Object_var TAO::Invocation_Base::forwarded_to_ [protected]

Forwarded object reference.

CORBA::Object_ptr TAO::Invocation_Base::otarget_ [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.

GIOP::ReplyStatusType TAO::Invocation_Base::reply_status_ [protected]

A GIOP reply status of the invocation.

bool TAO::Invocation_Base::response_expected_ [protected]

Is response expected?

TAO_Stub* TAO::Invocation_Base::stub_ [private]
CORBA::Object_ptr TAO::Invocation_Base::target_ [private]

The effective target on which the invocation is on.
