.. _class_VisualShaderNodeColorOp_property_operator:

.. rst-class:: classref-property

:ref:`Operator<enum_VisualShaderNodeColorOp_Operator>` **operator** = ``0``

.. rst-class:: classref-property-setget

- void **set_operator** **(** :ref:`Operator<enum_VisualShaderNodeColorOp_Operator>` value **)**

.. |virtual| replace:: :abbr:`virtual (This method should typically be overridden by the user to have any effect.)`
.. |const| replace:: :abbr:`const (This method has no side effects. It doesn't modify any of the instance's member variables.)`
.. |vararg| replace:: :abbr:`vararg (This method accepts any number of arguments after the ones described here.)`
.. |static| replace:: :abbr:`static (This method doesn't need an instance to be called, so it can be called directly using the class name.)`
