[Javaflow] Access to the resumed target of a Continuation

[Márcio Faria <fa...@ymail.com>]

Dear Javaflow's crew,

What is the recommended way to access the Runnable 'target' from a Continuation after calling 'Continuation.continueWith(....)' ? Suppose that Continuation was loaded from a file, so I don't have the reference to the original 'target' Object.

Under these conditions, do we have to resort to a 'pContext' object, which would then be set by the resumed Runnable 'target' itself? 

Do you anticipate any problem with the above approach? Is there a better way to get a reference to the resumed Runnable?

Thanks in advance,

Marcio

Your Runnable then needs to be Serializable and should get serialized
to disk with the continuation.
(see Stack.java)

Have a look at this TestCase.

http://svn.apache.org/viewvc/commons/sandbox/javaflow/trunk/src/test/java/org/apache/commons/javaflow/suite/SerializationTestCase.java?revision=733503

Nothing you should have to worry about.

cheers
