Detailed Description

ProxyPullConsumer.

Implement the CosEventChannelAdmin::ProxyPullConsumer interface, remember that this class is used to communicate with a PullSupplier, so, in effect, this is the ambassador for a supplier inside the event channel. = MEMORY MANAGMENT The object commits suicide when disconnect_pull_consumer() is called.

virtual

Activate in the POA.

CosEventComm::PullSupplier_ptr TAO_CEC_ProxyPullConsumer::apply_policy ( CosEventComm::PullSupplier_ptr s )

protected

Assigns the parameter to both supplier_ and nopolicy_supplier_, and applies policies (when appropriate) to supplier_.

void TAO_CEC_ProxyPullConsumer::cleanup_i ( void )

protected

Release the supplier.

void TAO_CEC_ProxyPullConsumer::connect_pull_supplier ( CosEventComm::PullSupplier_ptr pull_supplier )

virtual

void TAO_CEC_ProxyPullConsumer::deactivate ( void )

virtual

Deactivate from the POA.

void TAO_CEC_ProxyPullConsumer::disconnect_pull_consumer ( void )

virtual

CORBA::Boolean TAO_CEC_ProxyPullConsumer::is_connected ( void ) const

Return 0 if no supplier is connected...

CORBA::Boolean TAO_CEC_ProxyPullConsumer::is_connected_i ( void ) const

protected

The private version (without locking) of is_connected().

CORBA::Any * TAO_CEC_ProxyPullConsumer::pull_from_supplier ( void )

void TAO_CEC_ProxyPullConsumer::shutdown ( void )

virtual

The event channel is shutting down.

CosEventComm::PullSupplier_ptr TAO_CEC_ProxyPullConsumer::supplier ( void ) const

Return the consumer object reference. It returns nil() if it has not connected yet.

void TAO_CEC_ProxyPullConsumer::supplier ( CosEventComm::PullSupplier_ptr supplier )

protected

Set the supplier, used by some implementations to change the policies used when invoking operations on the supplier.

void TAO_CEC_ProxyPullConsumer::supplier_i ( CosEventComm::PullSupplier_ptr supplier )

protected

CORBA::Boolean TAO_CEC_ProxyPullConsumer::supplier_non_existent ( CORBA::Boolean_out disconnected )

Invoke the _non_existent() pseudo-operation on the supplier. If it is disconnected then it returns true and sets the <disconnected> flag.

CORBA::Any * TAO_CEC_ProxyPullConsumer::try_pull_from_supplier ( CORBA::Boolean_out has_event )

Pulls from the supplier, verifies that it is connected.
