Method Descriptions
-------------------

.. _class_VisualScriptNode_method_get_default_input_value:

.. rst-class:: classref-method

:ref:`Variant<class_Variant>` **get_default_input_value** **(** :ref:`int<class_int>` port_idx **)** |const|

Returns the default value of a given port. The default value is used when nothing is connected to the port.

.. rst-class:: classref-item-separator

----

.. _class_VisualScriptNode_method_get_visual_script:

.. rst-class:: classref-method

:ref:`VisualScript<class_VisualScript>` **get_visual_script** **(** **)** |const|

Returns the :ref:`VisualScript<class_VisualScript>` instance the node is bound to.

.. rst-class:: classref-item-separator

----

.. _class_VisualScriptNode_method_ports_changed_notify:

.. rst-class:: classref-method

void **ports_changed_notify** **(** **)**

Notify that the node's ports have changed. Usually used in conjunction with :ref:`VisualScriptCustomNode<class_VisualScriptCustomNode>` .

.. rst-class:: classref-item-separator

----

.. _class_VisualScriptNode_method_set_default_input_value:

.. rst-class:: classref-method

void **set_default_input_value** **(** :ref:`int<class_int>` port_idx, :ref:`Variant<class_Variant>` value **)**

Change the default value of a given port.

.. |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.)`
