Class SharedStateContribution

java.lang.Object

org.eclipse.xtext.ui.shared.contribution.SharedStateContribution

public final class SharedStateContribution
extends Object

A shared state contribution is used to obtain instances from a contributed injector. The injector is created as a child of the shared master injector. It does not allow JIT bindings since they would be contributed to the shared master. The framework uses the following contribution types internally:

• org.eclipse.xtext.builder.impl.QueuedBuildDataContribution
• org.eclipse.xtext.builder.impl.ToBeBuiltComputerContribution
• org.eclipse.xtext.builder.trace.StorageAwareTraceContribution
• IStorage2UriMapperContribution
• IResourceSetInitializer
• IEagerContribution
