Class DaemonProperties
java.lang.Object
|
+--org.w3c.jigsaw.daemon.DaemonProperties
- public class DaemonProperties
- extends java.lang.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 org.w3c.jigsaw.http package host
property can be set fro server1 to host1 and for server2 to host2.
This is done by defining server1.org.w3c.jigsaw.http.host
and server2.org.w3c.jigsaw.http.host
Each property can be monitored, to allow for dynamic reconfiguration of
the server.
