public interface PropertyType
extends java.io.Serializable

Represents a property type of a meta-object. This is an additional abstraction on top of the Java Class object to provide more flexible subtyping. All PropertyTypes will have a base Java class that they sub-type or represent. This is useful as a fall-back when a more specific handler is not available. Additionally, PropertyTypes can be used to test an Object's membership in the type family.
