[QVTO] Trace of transformation execution [message #98453]

Hi,

I'd like to get the trace of a transformation execution. Using the
QVTOTrace and the output model.
Currently, I found an execution tree for an object (the sequence of rules
from the main to the rule witch create the object) but due to some QVTO
particularity, some rules are missing (when a disjunct is used for
example, or a call in an init section).

Do a way exist to catch theses rules ? Where trace are generated/specified
in source code ?

In QVTOTrace, a property called "Runtime execution" is present, what is
its usage ? In every QVTOTrace I read, this property was never filled.

Best regards

Vincent

Hi Vincent,

A QVTO trace record is created every time a mapping body is executed. As
you have mentioned, the record is not created in other cases such as
when a mapping is invoked more than once with the same parameters
(including its context). In such cases the mapping is NOT executed,
therefore, the results are populated from the trace (available from the
previous mapping execution). Thus, answering your question whether there
is a way to catch these rules - from trace you can only see the mappings
which were executed and no way to get mapping invocations that didn't
cause mapping execution. If you anyways wish to do so, you should use
some user techniques such as flag properties located before/after the
mapping call, etc.

See org.eclipse.m2m.internal.qvt.oml.evaluator.TraceUtil class.

I suppose you meant "runtimeMappingOperation". This one is used in
runtime for trace checking for duplicate mapping invocation with the
same parameters and for resolveIn functions. It's containment is false
thus you didn't find it.
