end

#resolve(loader) ⇒ PTypeAliasType

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Called from the TypeParser once it has found a type using the Loader. The TypeParser will interpret the contained expression and the resolved type is remembered. This method also checks and remembers if the resolve type contains self recursion.

Parameters:

  • type_parser (TypeParser) —

    type parser that will interpret the type expression

  • loader (Loader::Loader) —

    loader to use when loading type aliases

Returns:
