obtain_pull_supplier

public ProxyPullSupplier obtain_pull_supplier()

Return a ProxyPullSupplier reference to be used to connect to a PullConsumer.

obtain_push_consumer

public ProxyPushConsumer obtain_push_consumer()

Return a ProxyPushConsumer reference to be used to connect to a PushSupplier.

obtain_push_supplier

public ProxyPushSupplier obtain_push_supplier()

push_event

protected void push_event(Any event)

Send event to all registered consumers.

_default_POA
