Example 1 with QueryVisitorStub

use of graphql.analysis.QueryVisitorStub in project graphql-java by graphql-java.

the class FieldValidationSupport method validateFieldsAndArguments.

static List<GraphQLError> validateFieldsAndArguments(FieldValidation fieldValidation, ExecutionContext executionContext) {
    Map<ResultPath, List<FieldAndArguments>> fieldArgumentsMap = new LinkedHashMap<>();
    QueryTraverser queryTraverser = QueryTraverser.newQueryTraverser().schema(executionContext.getGraphQLSchema()).document(executionContext.getDocument()).operationName(executionContext.getOperationDefinition().getName()).variables(executionContext.getVariables()).build();
    queryTraverser.visitPreOrder(new QueryVisitorStub() {

                // 
                // only fields that have arguments make any sense to placed in play
                // since only they have variable input
                FieldAndArguments fieldArguments = new FieldAndArgumentsImpl(env);
                ResultPath path = fieldArguments.getPath();
