Method Detail

MyType

public ProxyType MyType()

Specified by:

MyType in interface ProxySupplierOperations

Specified by:

MyType in class AbstractProxy

disconnect_pull_supplier

public void disconnect_pull_supplier()

Specified by:

disconnect_pull_supplier in interface PullSupplierOperations

disconnectClient

protected void disconnectClient()

Description copied from class: AbstractProxy

invoke the proxy specific disconnect method.

Specified by:

disconnectClient in class AbstractProxy

pull

public Any pull()
         throws Disconnected

Specified by:

pull in interface PullSupplierOperations

Throws:

Disconnected

try_pull

public Any try_pull(BooleanHolder hasEvent)
             throws Disconnected

Specified by:

try_pull in interface PullSupplierOperations

Throws:

Disconnected

deliverMessage

public void deliverMessage(Message message)

Deliver Event to the underlying Consumer. As our Consumer is a PullConsumer we simply put the Events in a Queue. The PullConsumer will pull the Events out of the Queue at a later time.

Specified by:

deliverMessage in interface MessageConsumer

connect_any_pull_consumer

public void connect_any_pull_consumer(PullConsumer consumer)
                               throws AlreadyConnected

Specified by:

connect_any_pull_consumer in interface ProxyPullSupplierOperations

Throws:

AlreadyConnected

getSubsequentFilterStages

public java.util.List getSubsequentFilterStages()

Description copied from interface: FilterStage

get FilterStages following this Node.

Specified by:

getSubsequentFilterStages in interface FilterStage

getMessageConsumer

public MessageConsumer getMessageConsumer()

Description copied from interface: FilterStage

get the associated MessageConsumer or null.

Specified by:

getMessageConsumer in interface FilterStage

hasMessageConsumer

public boolean hasMessageConsumer()

Description copied from interface: FilterStage

check if this FilterStage has a MessageConsumer associcated.

Specified by:

hasMessageConsumer in interface FilterStage

enableDelivery

public void enableDelivery()

Description copied from interface: MessageConsumer

activate deliveries. this MessageConsumer may invoke remote operations again.

Specified by:

enableDelivery in interface MessageConsumer

Overrides:

deliverPendingData

public void deliverPendingData()

Description copied from interface: MessageConsumer

process pending work. push events to its connected (Push)Consumer.

Specified by:

deliverPendingData in interface MessageConsumer

getServant

public Servant getServant()

activate

public Object activate()

Specified by:

activate in interface ManageableServant
