EXPORTS
connect_sequence_pull_consumer(SequenceProxyPullSupplier, PullConsumer) -> Reply
Types SequenceProxyPullSupplier = #objref
PullConsumer = #objref
Reply = ok | {'EXCEPTION', #'CosEventChannelAdmin_AlreadyConnected'{}}
This operation connects a PullConsumer to the target object. If a connection already exists an exception is raised.
pull_structured_events(SequenceProxyPullSupplier, MaxEvents) -> Reply
Types SequenceProxyPullSupplier = #objref
MaxEvents = long()
Reply = EventBatch | {'EXCEPTION', #'CosEventChannelAdmin_Disconnected'{}}
EventBatch = [StructuredEvent]
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}]
A client use this operation to pull next event sequence of maximum length MaxEvents . This operation is blocking and will not reply
until the requested amount of events can be delivered or the QoS property PacingInterval is reached. For more information see the
User's Guide .
try_pull_structured_events(SequenceProxyPullSupplier, MaxEvents) -> Reply
Types SequenceProxyPullSupplier = #objref
MaxEvents = long()
Reply = {EventBatch, HasEvent} | {'EXCEPTION', #'CosEventChannelAdmin_Disconnected'{}}
HasEvent = boolean()
EventBatch = [StructuredEvent]
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 an event sequence of the maximum length MaxEvents , but do not block if the target object have no events to
forward. The outparameter, HasEvent is true if the sequence contain any events.
disconnect_sequence_pull_supplier(SequenceProxyPullSupplier) -> ok
Types SequenceProxyPullSupplier = #objref
This operation cause the target object to close the connection and terminate.
