Constant for lazy query evaluation. When Query#execute() is called, the
query processor only chooses the best index and creates an iterator on
this index. Indexes and constraints are evaluated lazily when the
application iterates through the
com.db4o.ObjectSet resultset of the query.
Constant for snapshot query evaluation. When Query#execute() is called,
the query processor chooses the best indexes, does all index processing
and creates a snapshot of the index at this point in time. Non-indexed
constraints are evaluated lazily when the application iterates through
the
com.db4o.ObjectSet resultset of the query.
