Method Summary

EventPacket<?>	filterPacket(EventPacket<?> in) Subclasses implement this method to define custom processing.
java.lang.Object	getFilterState() should return the filter state in some useful form
void	initFilter() this should allocate and initialize memory: it may be called when the chip e.g.
boolean	isFilterEnabled() Filters can be enabled for processing.
void	propertyChange(java.beans.PropertyChangeEvent evt)
void	resetFilter() should reset the filter to initial state
void	setFilterEnabled(boolean yes) Overrides to avoid setting preferences for the enclosed filters
