[kepler-users] accsessing the current workflow

[Dan Higgins]

Hi Srinath,
    The current workflow doesn't really have an ID, but there is a 
concept of containment. All actors at the top level of a workflow (i.e. 
ignoring composite actors which create a hierarchy) have the same 
container. Parameters can be added to the workflow and those parameter 
values can be used by any actor in the workflow using the expression 
language. These parameters act as global variables.
    These shared parameters are usually examined before execution, 
however. They cannot be used to pass dynamic values (ie. values 
calculated when an actor fires).
    There is some discussion of this containment process in the Ptolemy 
users manuals (but I don't remember where).

    Hopefully this is some help.
