public interface HeadlessEventCollector
Interface for Knowledge Flow components that (typically) provide
an interactive graphical visualization to implement. This allows
events that would normally be processed to provide a graphical display
to be collected and retrieved when running in headless mode (perhaps on
a server for example). A copy of the component that is running with
access to a display can be passed the list of events in order to
construct its display-dependent output.
