CosNotifyChannelAdmin_­StructuredProxyPullSupplier This module implements the OMG CosNotifyChannelAdmin::StructuredProxyPullSupplier interface.

To get access to the record definitions for the structures use:

-include_lib("cosNotification/include/*.hrl").

This module also exports the functions described in:

CosNotifyComm_NotifySubscribe

CosNotification_QoSAdmin

CosNotifyFilter_FilterAdmin

CosNotifyChannelAdmin_ProxySupplier

 connect_structured_pull_consumer(StructuredProxyPullSupplier, PullConsumer) -> Reply Connect a consumer to the proxy StructuredProxyPullSupplier = #objref PullConsumer = #objref Reply = ok | {'EXCEPTION', #'CosEventChannelAdmin_AlreadyConnected'{}}

This operation connects a PullConsumer to the target object. If a connection already exists the AlreadyConnected exception is raised.

 pull_structured_event(StructuredProxyPullSupplier) -> Reply Pull a structured event from the proxy StructuredProxyPullSupplier = #objref Reply = StructuredEvent | {'EXCEPTION', #'CosEventChannelAdmin_Disconnected'{}} StructuredEvent = #'CosNotification_StructuredEvent'{header, filterable_data, remainder_of_body} header = EventHeader filterable_data = [#'CosNotification_Property'{name, value}] name = string() value = #any remainder_of_body = #any EventHeader = #'CosNotification_EventHeader'{fixed_header, variable_header} fixed_header = FixedEventHeader variable_header = OptionalHeaderFields FixedEventHeader = #'CosNotification_FixedEventHeader'{event_type, event_name} event_type = EventType event_name = string() EventType = #'CosNotification_EventType'{domain_name, type_name} domain_name = type_name = string() OptionalHeaderFields = [#'CosNotification_Property'{name, value}]

This operation pulls next event from the target object; if an event cannot be delivered this function blocks until an event arrives.

 try_pull_structured_event(StructuredProxyPullSupplier) -> Reply Try to pull a structured event from the proxy StructuredProxyPullSupplier = #objref Reply = {StructuredEvent, HasEvent} | {'EXCEPTION', #'CosEventChannelAdmin_Disconnected'{}} HasEvent = boolean() StructuredEvent = #'CosNotification_StructuredEvent'{header, filterable_data, remainder_of_body} header = EventHeader filterable_data = [#'CosNotification_Property'{name, value}] name = string() value = #any remainder_of_body = #any EventHeader = #'CosNotification_EventHeader'{fixed_header, variable_header} fixed_header = FixedEventHeader variable_header = OptionalHeaderFields FixedEventHeader = #'CosNotification_FixedEventHeader'{event_type, event_name} event_type = EventType event_name = string() EventType = #'CosNotification_EventType'{domain_name, type_name} domain_name = type_name = string() OptionalHeaderFields = [#'CosNotification_Property'{name, value}]

This operation try to pull next event from the target object. If no event have arrived an empty event is returned and the out parameter HasEvent is set to false. Otherwise, the boolean flag is set to true and an valid event is returned.

 disconnect_structured_pull_supplier(StructuredProxyPullSupplier) -> ok Close connection and terminate the proxy StructuredProxyPullSupplier = #objref

This operation cause the target object to close the connection and terminate.
