Class SOReflect

java.lang.Object
  spark.data.SObj
      spark.data.SOReflect

All Implemented Interfaces:

SO, SParented

public class SOReflect
extends SObj

This is a concrete implementation of SO that has special properties. Subclasses of SOReflect can be used to expose various fields of the subclass as attributes visible to SO. It also accepts fields that are not known to the subclass and stores them as well.

Any public field that is Double, Long, Boolean, String, SO or SA will be exposes as an SO attribute.

Any pair of getXX()/setXX(v) methods will be treated as the attribute XX.

The idea is to create a subclass of SOReflect and give it public fields or get/set methods to define a set of attributes.
