Value
|
|
==================================== ======================================
|
|
**Rule ID** GD0102
|
|
**Category** Usage
|
|
**Fix is breaking or non-breaking** Breaking - If the member type is changed
|
|
|
|
Non-breaking - If the ``[Export]`` attribute is removed
|
|
**Enabled by default** Yes
|
|
==================================== ======================================
|
|
|
|
Cause
|
|
-----
|
|
|
|
An unsupported type is specified for a member annotated with the ``[Export]``
|
|
attribute when a
|
|
:ref:`Variant-compatible type <c_sharp_variant_compatible_types>` is expected.
|
|
|
|
Rule description
|
|
----------------
|
|
|
|
Every exported member must be Variant-compatible so it can be marshalled by
|
|
the engine.
|
|
|
|
.. code-block:: csharp
|
|
|
|
class SomeType { }
|
|
|
|
// SomeType is not a valid member type because it doesn't derive from GodotObject,
|
|
// so it's not compatible with Variant.
|
|
[Export]
|
|
public SomeType InvalidProperty { get; set; }
|
|
|
|
// System.Int32 is a valid type because it's compatible with Variant.
|
|
[Export]
|
|
public int ValidProperty { get; set; }
|
|
|
|
How to fix violations
|
|
---------------------
|
|
|
|
To fix a violation of this rule, change the member's type to be Variant-compatible
|
|
or remove the ``[Export]`` attribute.
|
|
|
|
When to suppress warnings
|
|
-------------------------
|
|
|
|
Do not suppress a warning from this rule. Members with types that can't be marshalled
|
|
will result in runtime errors.
