CosNotifyChannelAdmin_SequenceProxyPullSupplier(3)

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:

    *   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.
