Method Summary

Modifier and Type	Method	Description
void	add(IObjectsList list, boolean shortest)
MultiIntersectedStoredList	createCopyForAlternatingThread()	create a shallow copy ready for alternating thread usage
int	getAlreadyMatchedFixedPropertyIndexPos()	if the scan is on a property index, currently supported for extended index
boolean	hasNext()
boolean	isAlreadyMatched()	is the entry returned already matched against the searching template currently is true if the underlying scan made by CacheManager::EntriesIter
boolean	isIterator()	is the list an iterator or basic list ?
boolean	isMultiList()
boolean	isMultiListsIterator()	does this iter contain multiple lists
T	next()
protected IScanListIterator<T>	prepareListIterator(IObjectsList list)
void	releaseScan()	release SLHolder for this scan
