## org.w3c.jigsaw.daemon
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.

Constructor Detail

### DaemonProperties

    public DaemonProperties(java.io.File configdir,
                            java.util.Properties props)

  Parameters:
    `props` - The global properties to use in all spaces.

Method Detail

### loadPropertySpace

    public ObservableProperties loadPropertySpace(java.lang.String id,
                                                  java.io.InputStream in)
                                           throws java.io.IOException

  Extend a property space.
  Parameters:
    `id` - The identifier of the property set to extend.
    `in` - The input stream containing Java properties to add.
  Throws:
    java.io.IOException - If the input stream couldn't be read.
