Examples with Node graphql.language.Node used on opensource projects

Example 1 with Node

use of graphql.language.Node in project graphql-java by graphql-java.

the class KnownDirectives method checkDirective.

@Override
public void checkDirective(Directive directive, List<Node> ancestors) {
    GraphQLDirective graphQLDirective = getValidationContext().getSchema().getDirective(directive.getName());
    if (graphQLDirective == null) {
        String message = String.format("Unknown directive %s", directive.getName());
        addError(ValidationErrorType.UnknownDirective, directive.getSourceLocation(), message);
        return;
    }
    Node ancestor = ancestors.get(ancestors.size() - 1);
    if (hasInvalidLocation(graphQLDirective, ancestor)) {
        String message = String.format("Directive %s not allowed here", directive.getName());
        addError(ValidationErrorType.MisplacedDirective, directive.getSourceLocation(), message);
    }
}
