Example 50 with ParserRule

use of org.eclipse.xtext.ParserRule in project xtext-core by eclipse.

the class OverriddenValueInspector method caseRuleCall.

@Override
public Boolean caseRuleCall(RuleCall object) {
    AbstractRule calledRule = object.getRule();
    if (calledRule == null || calledRule.eIsProxy() || calledRule instanceof TerminalRule || calledRule instanceof EnumRule)
        return Boolean.FALSE;
    ParserRule parserRule = (ParserRule) calledRule;
    if (GrammarUtil.isDatatypeRule(parserRule))
        return Boolean.FALSE;
    if (parserRule.isFragment()) {
        visitFragment(object);
        if (GrammarUtil.isMultipleCardinality(object))
            visitFragment(object);
    }
    if (!addVisited(parserRule))
        return Boolean.FALSE;
    Multimap<String, AbstractElement> prevAssignedFeatures = assignedFeatures;
    assignedFeatures = newMultimap();
    doSwitch(parserRule.getAlternatives());
    for (String feature : assignedFeatures.keySet()) prevAssignedFeatures.put(feature, object);
