dependency injection in Xtext source code [message #1017032]

Hello,

In the classes org.eclipse.xtext.xtext.ui.wizard.project.XtextProjectCreator and org.eclipse.xtext.ui.wizard.AbstractProjectCreator of the source code of Xtext, the three following fields are instantiated using dependency injection:

@Inject
@Named("file.extensions")
private String fileExtension;

@Inject
private Provider<PluginProjectFactory> projectFactoryProvider;

@Inject
private Provider<FeatureProjectFactory> featureProjFactoryProvider;

What are the classes in the source code of Xtext that specifies how to instantiate these three fields? I think that these classes should implement "com.google.inject.Module" or inherit from another class that implements "com.google.inject.Module". However, there are so many classes in the source code of XText that I have been unable to locate these classes.

Any help would be appreciated.

Thanks in advance for any answer.

Hi,

entrypoint for guice are: the activator in the ui project and the standalonesetup in the runtime project
they make use of yourdslruntimemodule and yourdsluimodule (and other modules)
have a look at
