com.bazaarvoice.jolt.jsonUtil.testdomain.QueryFilter
com.google.visualization.datasource.query.QueryFilter
A query filter. Any class that implements this interface can act as a filter, i.e., be the part of a query that decides for a given TableRow if that row is part of the result set. @author Yonatan B.Y.

de.fzi.herakles.strategy.component.QueryFilter
This is the Interface of the Query filter @author xu
mil.nga.giat.geowave.store.filter.QueryFilter
A simple filter interface to determine inclusion/exclusion based on a generic persistence encoding. Client-side filters will be given an AdapterPersistenceEncoding but distributable filters will be given a generic PersistenceEncoding.
net.sf.redmine_mylyn.api.query.QueryFilter
org.apache.cassandra.db.filter.QueryFilter
org.apache.lucene.search.QueryFilter
Constrains search results to only match those which also match a provided query. Results are cached, so that searches after the first on the same index using this filter are much faster.
This could be used, for example, with a {@link RangeQuery} on a suitablyformatted date field to implement date filtering. One could re-use a single QueryFilter that matches, e.g., only documents modified within the last week. The QueryFilter and RangeQuery would only need to be reconstructed once per day. @version $Id: QueryFilter.java,v 1.4 2003/09/16 12:52:10 otis Exp $

@author bfoster @version $Revision$
A query filter that allows user to filter results in a complex query
org.kie.remote.jaxb.gen.QueryFilter
org.projectforge.core.QueryFilter
Stores the expressions and settings for creating a hibernate criteria object. This template is useful for avoiding the need of a hibernate session in the stripes action classes. @author Kai Reinhard (k.reinhard@micromata.de)
