=========================

**Inherits:** :ref:`VisualShaderNode<class_VisualShaderNode>` **<** :ref:`Resource<class_Resource>` **<** :ref:`Reference<class_Reference>` **<** :ref:`Object<class_Object>`

**Inherited By:** :ref:`VisualShaderNodeExpression<class_VisualShaderNodeExpression>`

Base class for a family of nodes with variable amount of input and output ports within the visual shader graph.
