 org.mmbase.storage.search.implementation.ModifiableQuery
| ModifiableQuery | | public class ModifiableQuery implements SearchQuery(Code) | | A ModifiedQuery enables a modifiable lightweight copy of a
org.mmbase.storage.search.SearchQuery SearchQuery to be created
by wrapping the original query.
This class is provided primarily for use by core-, security- and
storage layer classes, in those rare cases where modifications may be
appropriate to a query before processing it.
The ModifiedQuery wraps the original query, and can be modified
without affecting the original query. Modifications are not validated, and
may lead to inconsistent data in the query (e.g. sorting on fields
that are not in the query), resulting in a query that can not be processed
by the storage.
Avoiding such inconsistencies is the responsibility of the user.
