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

the class SchemaGeneratorHelper method buildValue.

public Object buildValue(Value value, GraphQLType requiredType) {
    Object result = null;
    if (requiredType instanceof GraphQLNonNull) {
        requiredType = ((GraphQLNonNull) requiredType).getWrappedType();

        result = parseLiteral(value, (GraphQLScalarType) requiredType);
    } else if (value instanceof EnumValue && requiredType instanceof GraphQLEnumType) {

    } else if (value instanceof ArrayValue && requiredType instanceof GraphQLList) {
        ArrayValue arrayValue = (ArrayValue) value;
        GraphQLType wrappedType = ((GraphQLList) requiredType).getWrappedType();
        result = arrayValue.getValues().stream().map(item -> this.buildValue(item, wrappedType)).collect(Collectors.toList());
    } else if (value instanceof ObjectValue && requiredType instanceof GraphQLInputObjectType) {
        result = buildObjectValue((ObjectValue) value, (GraphQLInputObjectType) requiredType);
