Hi all,

i am currently working on my bachelor thesis which makes use of the tptp
tracing components (probably you read my question in the newsgroup).

My first attempt was to create my own profiler to collect execution data
(method entry/exit) to create a dynamic callgrapg from. Then one gave me the
hint to look at uml2sd which creates something like that.

I checked out the plugin "org.eclipse.tptp.platform.common.ui" and found
some classes reagarding creation of a SDView. What i did not find were
classes dealing with retreaving trace data (from whereever) to visualise.
Could you give me a more detailed pointer, please. I searched through the
code but was not successful right now.

What I would like to have is a callgraph of a JUnit-Testrun (whereas
profiling JUnit Tests will not be supported anymore, right? [read that in a
bug]). What i think i understood so far is the following:

- at first i have to create a trcaxmi file with the existing ExecutionFlow
Agent (probably by registering my own dataCollectionMechanism)
- then i have to notified by somethinf that profiling has finished and data
could be queried
- than i have to query this trcaxmi file (somehow) and create the callgraph
from, right?

Furthermore, is there any possibility to query the trace data online (as
events occur)? Or do i have to make the indirection via the file?

If anyone could give me some pointers to get started it would be much
appreciated.

Regards,

Thomas E.-E.
