The abstract type runtime information.
Whether or not the type is [`private`](https://haxe.org/manual/type-system-module-sub-types.html#define-private-type).
The full slash path of the .hx file containing the type. This might be `null` in case there is no such file, e.g. if the type is defined through a macro.
The documentation of the type. This information is only available if the compiler flag `-D use_rtti_doc` was in place. Otherwise, or if the constructor has no documentation, the value is `null`.
