Examples of org.datanucleus.store.mapped.expression.CollectionExpression

org.datanucleus.store.mapped.expression.CollectionExpression
An expression that represents some collection field in a query candidate class, or a collection field in an object linked from the candidate class by navigation.
When navigated through using contains(expr), the elements of the collection are relationally joined onto the query statement.

As this is a Collection Expression it works equally for Sets and Lists, and we use CollectionStore as the backing store interface, so that ListStore and SetStore are equally applicable. @version $Revision: 1.33 $
