Class Activator

java.lang.Object

org.avineas.fins.osgi.Activator

All Implemented Interfaces:

org.osgi.framework.BundleActivator

public class Activator
extends java.lang.Object
implements org.osgi.framework.BundleActivator

Bundle activator for OSGi based environment usage of the FINS bundle. When this bundle is started, it automatically starts a gateway for this machine on the default UDP port and handles automatically any units defined within the OSGi framework by tracking services. The activator looks for configuration data at PID fins.gateway. The following properties are accepted:

• port. If specified this is the UDP port the gateway will listen on. If blank, the gateway is shut down (or doesn't come up).
• remote.nodes. Contains a string with the map of FINS nodes to remote machine. Format is something like: 1/2=localhost:9001 2/4=remotenode:9002 (first part is the FINS network/node, second part the host and port, separated by an equals sign, multiple values are space separated).
• timeout. Contains the time-out in ms the gateway waits for responses from other nodes. Defaults to 3000 ms.
• tries. Contains the number of times a packet is sent before it is considered to be undeliverable. Defaults to 3.
