public abstract class Swiftlet extends Object
Swiftlets are components of a SwiftMQ router and are under control of the SwiftletManager.

Implementing classes overwrite the startup and shutdown method.

A Swiftlet is instantiated from the SwiftletManager. All Kernel Swiftlets are sharing one class loader, and every Extension Swiftlet has his own class loader.
