Hi,
Another question :-) for QVT
Is there any way that we can call call QVT from java code? Even further,
if we can, can we get the root (pointer) for the output model instance (in
memory), not a file?
Thanks.
David

Hi David,
Java API for transformation launching is
org.eclipse.m2m.qvt.oml.runtime.util.QvtoTransformationHelpe r class.
Usage examples can be found in 'org.eclipse.m2m.qvt.oml.tests' plugin.
Code snippet:
URI scriptUri = ..
List<EObject> inObjects = ..
TransfExecutionResult execResult = new
QvtoTransformationHelper(scriptUri).executeTransformation(in Objects,
Collections.<String, Object>emptyMap(), null);
Where 'scriptUri' can specify file, platform resource or bundled script
(using platform:/plugin/ form).
Transformation output extents are created in memory. Persistence is
responsibility of caller.
Regards,
Sergey
