Examples of org.apache.cayenne.DataObject.readNestedProperty()

org.apache.cayenne.DataObject.readNestedProperty()
Returns a value of the property identified by a property path. Supports reading both mapped and unmapped properties. Unmapped properties are accessed in a manner consistent with JavaBeans specification.
Property path (or nested property) is a dot-separated path used to traverse object relationships until the final object is found. If a null object found while traversing path, null is returned. If a list is encountered in the middle of the path, CayenneRuntimeException is thrown. Unlike {@link #readPropertyDirectly(String)}, this method will resolve an object if it is HOLLOW.
Examples:
- Read this object property:
  String name = (String)artist.readNestedProperty("name");
- Read an object related to this object:
  Gallery g = (Gallery)paintingInfo.readNestedProperty("toPainting.toGallery");
- Read a property of an object related to this object:
  String name = (String)painting.readNestedProperty("toArtist.artistName");
- Read to-many relationship list:
  List exhibits = (List)painting.readNestedProperty("toGallery.exhibitArray");
- Read to-many relationship in the middle of the path (throws exception):
  String name = (String)artist.readNestedProperty("paintingArray.paintingName");
