  org.exoplatform.commons.utils.PropertyManager

public class PropertyManager
extends java.lang.Object

A property manager that acts as a facade of the system properties. The manager has a cache that is only disabled if the property exo.product.developing is set to the false string. The cache usage is read once during the static initialization of the cache and it can be programmatically triggered by calling the refresh() method.
