Class RingSectionFilter

java.lang.Object

org.davic.mpeg.sections.SectionFilter

org.davic.mpeg.sections.RingSectionFilter

public class RingSectionFilter
extends SectionFilter

This class defines a section filter intended to be used to capture a continuous stream of MPEG-2 sections without needing to stop and re-arm a filter. A RingSectionFilter object has a pre-defined number of Section objects as part of it. Incoming sections are loaded sequentially into these Section objects. Filtering proceeds while empty Section objects remain. Applications wishing filtering to proceed indefinitely must use the setEmpty method of the Section object to mark Section objects as empty before the filling process reaches them. If the filtering process reaches a non-empty Section object, it will terminate at that point. On each occasion when startFiltering is called, the sections will be captured starting from the beginning of the array.

All sections in a ring section filter are initialised to empty when the ring section filter is first created. Clearing them to empty any time after this is the responsibility of the application. Starting a ring section filter shall not clear any of the sections to empty.
