Detailed Description

ProxyPushConsumer.

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

const

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

void TAO_CEC_ProxyPushConsumer::supplier ( CosEventComm::PushSupplier_ptr  supplier )

protected

protected

CORBA::Boolean TAO_CEC_ProxyPushConsumer::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.

Member Data Documentation

bool TAO_CEC_ProxyPushConsumer::connected_

private

If the flag is true then we are connected, notice that the supplier can be nil.

PortableServer::POA_var TAO_CEC_ProxyPushConsumer::default_POA_

private

Store the default POA.

TAO_CEC_EventChannel* TAO_CEC_ProxyPushConsumer::event_channel_

private

The supplier admin, used for activation and memory managment.

ACE_Lock* TAO_CEC_ProxyPushConsumer::lock_

private

The locking strategy.

CosEventComm::PushSupplier_var TAO_CEC_ProxyPushConsumer::nopolicy_supplier_

private

The supplier without any policies applied.

CORBA::ULong TAO_CEC_ProxyPushConsumer::refcount_

private

The reference count.

CosEventComm::PushSupplier_var TAO_CEC_ProxyPushConsumer::supplier_

private

The supplier – use apply_policy() instead of assigning directly to supplier_. This will keep supplier_ and nopolicy_supplier_ in sync.
