Is there a way to get a list of types already loaded from the schema?

[abdullahseba]

I am trying to load types that have not already been loaded in the PHP-defined schema so that they can be used in the schema language. The problem is, setTypes() doesn't accept any types which have already been loaded in the schema and setTypeLoader() requires all types including those defined in the schema language. There doesn't seem to be a way of either extracting the types from the schema language for setTypeLoader() or a way of getting a list of already loaded types to be excluded in setTypes().

Any ideas for this?

There sure is. This library has both higher level utilities to do it (GraphQL\Utils\BuildSchema), as well as lower level primitives (GraphQL\Language\Parser + building types of the AST nodes).
