Using IncQuery in standalone EMF configurations

IncQuery can now also be used in standalone EMF configurations, i.e. outside of the Eclipse/OSGi environment (e.g. in command line apps or Java Enterprise applications).  You only need to add a single line of hand-written code per pattern, to initialize the generated pattern builder as follows:

BuilderRegistry.getContributedStatelessPatternBuilders().put(
	EClassMatcher.FACTORY.getPatternName(),
	new PatternBuilderForeClass()); // name of generated pattern builder class, resides inside the patternbuilders.XXX package

This technique is illustrated in the code of the ECore Queries example above, available from the SVN repository at

• https://viatra.inf.mit.bme.hu/svn/incquery/trunk/examples/code/ecorequery/hu.bme.mit.ecorequery/src/standalone/StandaloneApp.java

In case you wish to use derived features as well (see derived features, ecore queries also depends on this since many features of the Ecore metamodel are derived/volatile), you also need the following code line:

WellbehavingDerivedFeatureRegistry.registerWellbehavingDerivedPackage(
	EPackage.Registry.INSTANCE.getEPackage("http://www.eclipse.org/emf/2002/Ecore"));
