Class DefaultUniqueNameContext.Global

java.lang.Object

org.eclipse.xtext.validation.DefaultUniqueNameContext.BaseContextProvider

org.eclipse.xtext.validation.DefaultUniqueNameContext.BaseGlobalContextProvider

org.eclipse.xtext.validation.DefaultUniqueNameContext.Global

All Implemented Interfaces:

IsAffectedExtension, INamesAreUniqueValidationHelper.ContextProvider

Enclosing class:

DefaultUniqueNameContext

public static class DefaultUniqueNameContext.Global
extends DefaultUniqueNameContext.BaseGlobalContextProvider

Provide a context for the entire index.

Drawback: If a resoure in a project A introduces a duplication with a resource in project B, an incremental build of A may fail to notify B, if B is a dependency of A. Triggering a clean build in B will subsequently create the validation problem / fix the validation problem there, too but in Eclipse, the incremental build will not provide the same level of consistency.

tryGetContext

public INamesAreUniqueValidationHelper.Context tryGetContext(org.eclipse.emf.ecore.resource.Resource resource,
                                                             org.eclipse.xtext.util.CancelIndicator cancelIndicator)

Description copied from interface: INamesAreUniqueValidationHelper.ContextProvider

Obtain the context of the unique name validation for the given resource. May return null.

isAffected

public boolean isAffected(java.util.Collection<IResourceDescription.Delta> deltas,
                          IResourceDescription candidate,
                          IResourceDescriptions context)

Description copied from interface: IsAffectedExtension

Answers true if the given candidate is impacted by the given delta beyond the default linking semantics. If the default answered true, an extension is never asked, e.g. it cannot contradict the default implementation or other extensions by turning their yes into a no.
