Public Methods
public
boolean
isCacheable
()
This method is a hint for CachingWrapperFilter
, if this DocIdSet
should be cached without copying it into a BitSet. The default is to return
false
. If you have an own DocIdSet
implementation
that does its iteration very effective and fast without doing disk I/O,
override this method and return true.
