The Javaflow Component  Sometimes it is usefull if we can
capture the state of the application, its stack of function
calls, which includes local variables, the global variables and
the program counter, and save them into an object. If this
object would give us the ability to restart the processing from
the point stored in it.  A continuation is exactly the type of
object that we need. Think of a continuation as an object that,
for a given point in your program, contains a snapshot of the
stack trace, including all the local variables, and the program
counter. You can not only store these things in the continuation
object, but also restore the execution of the program from a
continuation object. This means that the stack trace and the
program counter of the running program become the ones stored in
a continuation.  Continuations are powerful concepts from the
world of functional languages, like Scheme, but they are
becoming popular in other languages as well.   See the downloads
