Example 31 with OrderByField

use of org.jaffa.components.finder.OrderByField in project jaffa-framework by jaffa-projects.

the class GraphCriteria method returnQueryClause.

/**
 * Return the real retrieve clause that will be executed for this query.
 * <p>
 * When this is used for a sub-query, a nestedClause will be passed in that
 * will already have the table name set, and have criteria that will limit
 * the query to only retrive child records of the already retrieved parent record.
 * <p>
 * THIS MUST BE OVERRIDDEN BY THE SUPERCLASS
 * <p>
 * The abstract implementation can be used to initially create a Criteria object
 * populated with the default fields on the base class (start, limit, orderBy)
 * <p>
 * If you are having issues with flexCriteriaBean results missing from the generated criteria,
 * then you may need redirect the caller to invoke buildQueryCriteria as opposed to this method.
 * See the notes for buildQueryCriteria for more information!
 *
 * @param nestedClause Minimal criteria used to retrieve the nested object. Will be null for the root query.
 * @return return the generated clause
