CosNotifyChannelAdmin_SequenceProxyPullSupplier(3erl) | Erlang Module Definition | CosNotifyChannelAdmin_SequenceProxyPullSupplier(3erl) |
NAME¶
CosNotifyChannelAdmin_SequenceProxyPullSupplier - This module implements the OMG CosNotifyChannelAdmin::SequenceProxyPullSupplier interface.DESCRIPTION¶
To get access to the record definitions for the structures use:- *
- CosNotifyComm_NotifySubscribe
- *
- CosNotification_QoSAdmin
- *
- CosNotifyFilter_FilterAdmin
- *
- CosNotifyChannelAdmin_ProxySupplier
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.
