Hi Bill:

a good plan. More detail below.

Here is my proposal:

1. The first task focusses on generating traversal beans only.
1.1. Develop a shrinkage plan (the opposite of a growth plan) for
the APPC cd. The one we have is way too large but also to small:
it misses the Mapping, etc.

1.2  In parallel: Write a traversal bean manually for the capacity checking
     example. Generate a Demeter/Java environment for the cd
     and write the traversal bean manually for that Java program.
     The traversal bean will emit events as it traverses
     a container.
1.3  Now that you have an example, write an adaptive program
     for the first growth phase of your cd to:
     1.3.1 Extract the traversal strategies from an APPC and a map.
     There are two kinds of traversal strategies operating
     on the concrete class graph:
     1.3.1.1 Traversals in adaptive methods
     1.3.1.2 Traversals from the map
     For each of those traversal strategies generate a bean as follows:
     Store the traversal graph in the bean.
     Write a generic traversal graph interpreter that takes 
     as input a traversal graph and an object and it
     generates the traversal events of the bean:
     before A
     after A
     before -> A,b,B
     after -> A,b,B
     for construction classes and edges.
     See paper with Boaz Patt-Shamir for specification.

1.3  The same for the adapter beans.
1.4  the same for the APPC beans if time permits.

See above: First test the traversal beans.

Simply copy it.

we use CVS in Demeter/Java. Are you familiar with that?
cvs  is  a front end to the rcs(1) revision control system

>What version of JavaBean to write to (assuming 1.01)?

I guess the latest and greatest from SUN. But David
might have more input on this.
