Class SequencePullSupplierPOATie

The SequencePullSupplier interface supports operations which enable suppliers to transmit sequences of Structured Events by the pull model. It also defines an operation which can be invoked to disconnect the pull supplier from its associated consumer. In addition, the SequencePullSupplier interface inherits the NotifySubscribe interface described above, enabling a notification consumer to inform an instance supporting this interface whenever there is a change to the types of events it is interested in receiving. Note that an object supporting the SequencePullSupplier interface can transmit events which can potentially be received by any consumer connected to the channel, including those which consume events in a form other than a sequence of Structured Events. How events supplied to the channel in the form of a sequence of Structured Events are internally mapped into different forms for delivery to consumers which receive events in a form other than the a sequence of Structured Events is summarized in Table 2-2.
