com.volantis.xml.pipeline.sax.flow.FlowController

A pipeline object that can control the flow of events through the pipeline.

The flow control mechanism is intended to allow the flow of events to be influenced at the earliest possible point in the pipeline. The ideal of course is for the events never to even be introduced into the pipeline at all but that is dependent on the source of the events being able to handle flow control.

Just because a flow controller receives an event indicating that flow control has started does not mean that it will actually be required to perform any flow control. It all depends on whether it is responsible for processing or generating events during the period in which the pipeline is in flow control mode.
