Constructor Summary

ProxyPushConsumerImpl(EventChannelImpl channel)
Constructor

Method Summary

void	connect_push_supplier(PushSupplier pushSupplier) A nil object reference may be passed to the connect_push_supplier operation; if so a channel cannot invoke the disconnect_push_supplier operation on the supplier; the supplier may be disconnected from the channel without being informed.
void	disconnect_push_consumer() The disconnect_push_consumer operation terminates the event communication; it releases resources used at the consumer to support the event communication.
void	push(org.omg.CORBA.Any event) A supplier communicates event data to the consumer by invoking the push operation and passing the event data as a parameter.

Method Detail

connect_push_supplier

public void connect_push_supplier(PushSupplier pushSupplier)
                           throws AlreadyConnected

A nil object reference may be passed to the connect_push_supplier operation; if so a channel cannot invoke the disconnect_push_supplier operation on the supplier; the supplier may be disconnected from the channel without being informed.

Parameters:

pushSupplier - the push supplier to connect

Throws:

AlreadyConnected - If the ProxyPushConsumer is already connected to a PushSupplier, then the AlreadyConnected exception is raised.

push

public void push(org.omg.CORBA.Any event)
          throws Disconnected

A supplier communicates event data to the consumer by invoking the push operation and passing the event data as a parameter.

Parameters:

event - The event data to pass to consumers.

Throws:

Disconnected - If the event communication has already been disconnected, the Disconnected exception is raised.

disconnect_push_consumer

public void disconnect_push_consumer()

The disconnect_push_consumer operation terminates the event communication; it releases resources used at the consumer to support the event communication. The PushConsumer object reference is disposed.
