메소드 설명
reduceQuery ( Youshido\GraphQL\Execution\Context\ExecutionContextInterface $executionContext, array $reducers ) Apply all of $reducers to this query. Example reducer operations: checking for maximum query complexity, performing look-ahead query planning, etc.

메소드 설명
doVisit ( Query $query, AbstractType $currentLevelSchema, AbstractQueryVisitor $reducer ) Entry point for the walkQuery routine. Execution bounces between here, where the reducer's ->visit() method is invoked, and walkQuery where we send in the scores from the visit call.
walkQuery ( Query | Field | Youshido\GraphQL\Parser\Ast\Interfaces\FragmentInterface $queryNode, Youshido\GraphQL\Field\FieldInterface $currentLevelAST ) : Generator Coroutine to walk the query and schema in DFS manner (see AbstractQueryVisitor docs for more info) and yield a tuple of (queryNode, schemaNode, childScore)

walkQuery() 보호된 메소드

childScore costs are accumulated via values sent into the coroutine. Most of the branching in this function is just to handle the different types in a query: Queries, Unions, Fragments (anonymous and named), and Fields. The core of the function is simple: recurse until we hit the base case of a Field and yield that back up to the visitor up in doVisit.
