```
public class PropertyQuery<V>
extends Object
```
Queries a target class for properties that match certain criteria. A property may either be a private or public field, declared by the target class or inherited from a superclass, or a public method declared by the target class or inherited from any of its superclasses. For properties that are exposed via a method, the property must be a JavaBean style property, i.e. it must provide both an accessor and mutator method according to the JavaBean specification.

This class is not thread-safe, however the result returned by the getResultList() method is.
