  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");
