I can see "continuations" as a sort of an inversion of the classic finite state machine computer algorithm (Sedgewick et al) It is all Iinteresting stuff. In essence it is still a state machine of sorts but captures a massively big state, the virtual machine execution state, instead of a smaller finite state. http://cocoon.apache.org/2.1/userdocs/flow/continuations.html What happens below the surface? Some sort of passivation and activation algorithm. Nice idea. > > The Apache Struts team is pleased to announce the adoption of > its latest > subproject, Struts Flow, a continuations-based approach to complex web > workflows.
