[phpCallGraph-general] Getting depth of routines for a UML Graph Sequence Diagram

[<Ma...@Cl...>]

Falko

It just occurred to me:

phpcallgraph does a lexical investigation (sequential as appears in
the source file) of the methods in a class. This does not do a
traversal according to how the methods are called.

It does hold an overview of the relationships after it has finished
(but doesn't know what's beyond the next layer during the
startFunction() and endFunction). During destruct, its seen
everything.  We know it knows because it passes all these
relationships to dot.

So, during destruct it would be possible to ask for a tree of
depended-upon methods for a given method. It would be possible to
visit each entry point method and to get all "dependent routines" that
need to be shown.

A question would be to what depth of dependents we would want to show.

Does my logic make sense?

Thanks,
   Martin.
