NAME

CosNotifyChannelAdmin_SequenceProxyPullSupplier - This module implements the OMG CosNotifyChannelAdmin::SequenceProxyPullSupplier interface.

DESCRIPTION

To get access to the record definitions for the structures use:
 
-include_lib("cosNotification/include/*.hrl").
This module also exports the functions described in:
*

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.
