Class PropertyCache

java.lang.Object
  com.calitha.reflect.PropertyCache

public class PropertyCache
extends Object

The PropertyCache is used to store information about the field/properties in classes and cache them so that they can retrieved very fast at a later time.

Only fields that have both a setter and getter are stored.

The singleton pattern makes sure that only one cache exists for the application.

The PropertyCache is thread-safe to use.
