Currently, the setter methods in the TypedProperties class, such as setInt("answer.to.everything", 42) have a void return type. We propose to make them return the TypedProperties object from which they are called, which will allow setting multiple properties of diffferent types in a single call chain. For example:

// get the configuration
TypedProperties config = JPPFConfiguration.getProperties();
// set the connection properties programmatically
config.setBoolean("jppf.discovery.enabled", false)
  .setString("jppf.drivers", "driver1")
  .setString("driver1.jppf.server.host", "www.myhost.com")
  .setInt("driver1.jppf.server.port", 11111);

This should have no impact on existing code, since we're not actually changing the signature of these methods, not even if they are accessed via reflection.
