Examples with ParserOptions graphql.parser.ParserOptions used on opensource projects

Example 1 with ParserOptions

use of graphql.parser.ParserOptions in project graphql-java by graphql-java.

the class ParseAndValidate method parse.

/**
 * This can be called to parse (but not validate) a graphql query.
 *
 * @param executionInput the input containing the query
 *
 * @return a result object that indicates how this operation went
 */
public static ParseAndValidateResult parse(ExecutionInput executionInput) {
    try {
        // 
        // we allow the caller to specify new parser options by context
        ParserOptions parserOptions = executionInput.getGraphQLContext().get(ParserOptions.class);
        Parser parser = new Parser();
        Document document = parser.parseDocument(executionInput.getQuery(), parserOptions);
        return ParseAndValidateResult.newResult().document(document).variables(executionInput.getVariables()).build();
    } catch (InvalidSyntaxException e) {
        return ParseAndValidateResult.newResult().syntaxException(e).variables(executionInput.getVariables()).build();
    }
}

Example 2 with ParserOptions

use of graphql.parser.ParserOptions in project graphql-java by graphql-java.

the class SchemaParser method parseImpl.

private TypeDefinitionRegistry parseImpl(Reader schemaInput, ParserOptions parseOptions) {
    try {
        if (parseOptions == null) {
            // for SDL we don't stop how many parser tokens there are - it's not the attack vector
            // to be prevented compared to queries
            parseOptions = ParserOptions.getDefaultParserOptions().transform(opts -> opts.maxTokens(Integer.MAX_VALUE));
        }
        Parser parser = new Parser();
        Document document = parser.parseDocument(schemaInput, parseOptions);
        return buildRegistry(document);
    } catch (InvalidSyntaxException e) {
        throw handleParseException(e.toInvalidSyntaxError());
    }
}

Example 3 with ParserOptions

use of graphql.parser.ParserOptions in project graphql-maven-plugin-project by graphql-java-generator.

the class DocumentParser method parseDocuments.

/**
 * The main method of the class: it graphqlUtils.executes the generation of the given documents
 *
 * @param documents
 *            The GraphQL definition schema, from which the code is to be generated
 * @return
