[news.eclipse.modeling.m2m] Re: [QVT] Call QVT from Java code/command li

[Sergey Boyko <sboyko@xxxxxxxxxxx>]

Hi David,

Java API for transformation launching is 
org.eclipse.m2m.qvt.oml.runtime.util.QvtoTransformationHelper 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(inObjects, 
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
