Class w3c.jigsaw.daemon.DaemonProperties

java.lang.Object
   |
   +----w3c.jigsaw.daemon.DaemonProperties

public class DaemonProperties
extends Object

Subclass of Properties, to deal with daemon specific usage of them. This class refines the basic Properties class, in order to tune them for ServerHandler specific needs:

Properties can be observed through the PropertyMonitoring interface,
Properties are multiplexed according to the server identifier. Two servers can rely on the same set of properties, but each of them can have its own property value. Eg the w3c.jigsaw.http package host property can be set fro server1 to host1 and for server2 to host2. This is done by defining server1.w3c.jigsaw.http.host and server2.w3c.jigsaw.http.host

Each property can be monitored, to allow for dynamic reconfiguration of the server.

Parameters:: id - The identifier for a property set space.
Returns:: An ObservableProperties instance, or null.
