public class ConfigSwitch

extends Contract

The ConfigurationSwitch contract. This contract defines the following service at the reactor:

PacketFilterConfiguration

The initiator sends a message that consists of:

1. the filter bank ID (int),
2. the filter ID in the bank (int), and
3. the request (Object).

The reactor will dispatch the request to the corresponding packet filter in the core service layer.

This class also provides a static method (configure(...)) to facilitate conducting the above service from the specified port. The method is particularly useful in implementing a (signaling) protocol that needs to configure the packet filters in the core service layer.
