the class DataTransformer method buildGraphFromDomain.

/**
 * Mould data from domain object and its related objects into a new JavaBean based
 * domain object graph, based on the defined mapping rules.
 *
 * @param source           Source object to mould data from, typically extends Persistent
 * @param target           Target object to mould data to, typically extends GraphDataObject
 * @param graph            The mapping class with the rules of how to map this source object
 * @param filter           Filter object that it is used to control what fields are populated or the target objects
 * @param objectPath       The path of this object being processed. This identifies possible parent
 *                         and/or indexed entries where this object is contained.
 * @param includeKeys      true if key fields should be included in results regardless of the filters
 * @param originalCriteria the original graph criteria.
 * @param handler          Possible bean handler to be used when processing this source object graph
 * @throws ApplicationExceptions Thrown if one or more application logic errors are generated during moulding
 * @throws FrameworkException    Thrown if any runtime moulding error has occured.
