Cause
|
|
-----
|
|
|
|
A generic type is annotated with the ``[GlobalClass]`` attribute.
|
|
|
|
Rule description
|
|
----------------
|
|
|
|
The Godot editor assumes every :ref:`global class <doc_c_sharp_global_classes>`
|
|
is instantiable, but generic types can't be instantiated because the type
|
|
arguments are unbound.
|
|
|
|
.. code-block:: csharp
|
|
|
|
// This type is a valid global class because it's not generic.
|
|
[GlobalClass]
|
|
class SomeType : Node { }
|
|
|
|
// This type is not a valid global class because it's generic.
|
|
[GlobalClass]
|
|
class SomeGenericType<T> { }
|
|
|
|
How to fix violations
|
|
---------------------
|
|
|
|
To fix a violation of this rule, change the type to remove the generic type parameters
|
|
or remove the ``[GlobalClass]`` attribute.
|
|
|
|
When to suppress warnings
|
|
-------------------------
|
|
|
|
Do not suppress a warning from this rule. Adding the ``[GlobalClass]`` to a
|
|
generic type is an easy mistake to make and this warning helps users realize
|
|
that it may result in unexpected errors.
