attribute
- the attribute to act on.from

if the range is left-closed,
false
otherwise.to
- the upper/right range bound.toInclusive
- true

otherwise.public Set<QueryableEntry> filter(QueryContext queryContext)
IndexAwarePredicate
The query engine assumes this method produces the result set faster than a simple evaluation of the predicate on every entry.

queryContext
- the query context to access the indexes. The passed
query context is valid only for a duration of a single
call to the method.protected boolean applyForSingleAttributeValue(Comparable value)
