TextServerExtension
===================
**继承：** :ref:`TextServer<class_TextServer>` **<** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`
**派生：** :ref:`TextServerAdvanced<class_TextServerAdvanced>`, :ref:`TextServerDummy<class_TextServerDummy>`, :ref:`TextServerFallback<class_TextServerFallback>`
自定义 :ref:`TextServer<class_TextServer>` 实现（插件）的基类。
.. rst-class:: classref-introduction-group
描述
----
外部的 :ref:`TextServer<class_TextServer>` 实现应该继承这个类。
