Examples of QueryChain

org.apache.cayenne.query.QueryChain
A Query decorator for a collection of other queries. Note that QueryChain will always return DataRows (that is if it returns data), as it has no way of knowing how to convert the results to objects. @since 1.2

Examples of org.apache.cayenne.query.QueryChain

        runInTransaction(new Transformer() {


            public Object transform(Object input) {
                new DataDomainLegacyQueryAction(
                        DataDomain.this,
                        new QueryChain(queries),
                        callback).execute();
                return null;
            }
