org.eclipse.xtext.validation

Class AbstractDeclarativeValidator

java.lang.Object

org.eclipse.xtext.validation.AbstractInjectableValidator

org.eclipse.xtext.validation.AbstractDeclarativeValidator

All Implemented Interfaces:

org.eclipse.emf.ecore.EValidator, ValidationMessageAcceptor

Direct Known Subclasses:

ImportUriValidator, NamesAreUniqueValidator, XtextValidator

public abstract class AbstractDeclarativeValidator
extends AbstractInjectableValidator
implements ValidationMessageAcceptor

Allows subclasses to specify invariants in a declarative manner using Check annotation. Example:

 @Check
 void checkName(ParserRule rule) {
        if (!toFirstUpper(rule.getName()).equals(rule.getName())) {
                warning("Name should start with a capital.", XtextPackage.Literals.ABSTRACT_RULE__NAME);
        }
 }
