Detailed Description

Implementation of the PortableServer::Current object.

Objects of this class hold state information regarding the current POA invocation. Savvy readers will notice that this contains substantially more methods than the POA spec shows; they exist because the ORB either (a) needs them or (b) finds them useful for implementing a more efficient ORB. The intent is that instances of this class are held in Thread-Specific Storage so that upcalls can get context information regarding their invocation. The POA itself must insure that all <set_*> operations are performed in the execution thread so that the proper <TAO_POA_Current> pointer is obtained from TSS.

Constructor & Destructor Documentation

TAO::Portable_Server::POA_Current_Impl::POA_Current_Impl ( void )

Member Function Documentation

PortableServer::ObjectId * TAO::Portable_Server::POA_Current_Impl::get_object_id ( void )

Return pointer to the object id through which this was invoked. This may be necessary in cases where a <Servant> is serving under the guise of multiple object ids.

PortableServer::POA_ptr TAO::Portable_Server::POA_Current_Impl::get_POA ( void )

Return pointer to the invoking POA. Raises the CORBA::NoContext exception.

CORBA::Object_ptr TAO::Portable_Server::POA_Current_Impl::get_reference ( void )

This operation returns a locally manufactured reference to the object in the context of which it is called.

PortableServer::Servant TAO::Portable_Server::POA_Current_Impl::get_servant ( void )

Returns a reference to the servant that hosts the object in whose context it is called.

void TAO::Portable_Server::POA_Current_Impl::object_id ( const PortableServer::ObjectId & id )

Set the object ID.

const PortableServer::ObjectId & TAO::Portable_Server::POA_Current_Impl::object_id ( void ) const

Get the object ID.

void TAO::Portable_Server::POA_Current_Impl::object_key ( const TAO::ObjectKey & key )

Set the object key.

const TAO::ObjectKey & TAO::Portable_Server::POA_Current_Impl::object_key ( void ) const

Get the object key.

void TAO::Portable_Server::POA_Current_Impl::operator= ( const POA_Current_Impl & )

private

TAO_ORB_Core & TAO::Portable_Server::POA_Current_Impl::orb_core ( void ) const

ORB Core for this current.

void TAO::Portable_Server::POA_Current_Impl::poa ( ::TAO_Root_POA * p )

Set the POA implementation.

TAO_Root_POA * TAO::Portable_Server::POA_Current_Impl::poa ( void ) const

Get the POA implemantation.

POA_Current_Impl * TAO::Portable_Server::POA_Current_Impl::previous ( void ) const

Return the previous current implementation.

void TAO::Portable_Server::POA_Current_Impl::priority ( CORBA::Short priority )

Set the priority for the current upcall.

CORBA::Short TAO::Portable_Server::POA_Current_Impl::priority ( void ) const

Get the priority for the current upcall.

void TAO::Portable_Server::POA_Current_Impl::replace_object_id ( const PortableServer::ObjectId & system_id )

Just replace the object id smartly.

void TAO::Portable_Server::POA_Current_Impl::servant ( PortableServer::Servant servant )

Set the servant for the current upcall.

PortableServer::Servant TAO::Portable_Server::POA_Current_Impl::servant ( void ) const

Get the servant for the current upcall.

void TAO::Portable_Server::POA_Current_Impl::setup	(	::TAO_Root_POA *	impl,
		const TAO::ObjectKey &	key
	)

Setup the current.

void TAO::Portable_Server::POA_Current_Impl::teardown ( void )

Teardown the current for this request.

Member Data Documentation

PortableServer::ObjectId TAO::Portable_Server::POA_Current_Impl::object_id_

protected

The object ID of the current context. This is the user id and not the id the goes into the IOR. Note also that unlike the object_key, this field is stored by value.

CORBA::Octet TAO::Portable_Server::POA_Current_Impl::object_id_buf_[TAO_POA_OBJECT_ID_BUF_SIZE]

protected

In order to avoid memory allocations, we will populate the object id with this buffer.

const TAO::ObjectKey* TAO::Portable_Server::POA_Current_Impl::object_key_

protected

The object key of the current context.

::TAO_Root_POA* TAO::Portable_Server::POA_Current_Impl::poa_

protected

The POA implementation invoking an upcall.

POA_Current_Impl* TAO::Portable_Server::POA_Current_Impl::previous_current_impl_

protected

Current previous from <this>.
