EditorDebuggerPlugin
====================

**Inherits:** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`

A base class to implement debugger plugins.

.. rst-class:: classref-introduction-group

Description
-----------

**EditorDebuggerPlugin** provides functions related to the editor side of the debugger.

To interact with the debugger, an instance of this class must be added to the editor via :ref:`EditorPlugin.add_debugger_plugin<class_EditorPlugin_method_add_debugger_plugin>`.

Once added, the :ref:`_setup_session<class_EditorDebuggerPlugin_method__setup_session>` callback will be called for every :ref:`EditorDebuggerSession<class_EditorDebuggerSession>` available to the plugin, and when new ones are created (the sessions may be inactive during this stage).

You can retrieve the available :ref:`EditorDebuggerSession<class_EditorDebuggerSession>`\ s via :ref:`get_sessions<class_EditorDebuggerPlugin_method_get_sessions>` or get a specific one via :ref:`get_session<class_EditorDebuggerPlugin_method_get_session>`.

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

.. _class_EditorDebuggerPlugin_method__capture:

.. rst-class:: classref-method

:ref:`bool<class_bool>` **_capture** **(** :ref:`String<class_String>` message, :ref:`Array<class_Array>` data, :ref:`int<class_int>` session_id **)** |virtual|

Override this method to process incoming messages. The ``session_id`` is the ID of the :ref:`EditorDebuggerSession<class_EditorDebuggerSession>` that received the message (which you can retrieve via :ref:`get_session<class_EditorDebuggerPlugin_method_get_session>`).

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

----

.. _class_EditorDebuggerPlugin_method__has_capture:

.. rst-class:: classref-method

:ref:`bool<class_bool>` **_has_capture** **(** :ref:`String<class_String>` capture **)** |virtual| |const|

Override this method to enable receiving messages from the debugger. If ``capture`` is "my_message" then messages starting with "my_message:" will be passes to the :ref:`_capture<class_EditorDebuggerPlugin_method__capture>` method.

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

----

.. _class_EditorDebuggerPlugin_method__setup_session:

.. rst-class:: classref-method

void **_setup_session** **(** :ref:`int<class_int>` session_id **)** |virtual|

Override this method to be notified whenever a new :ref:`EditorDebuggerSession<class_EditorDebuggerSession>` is created (the session may be inactive during this stage).

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

----

.. _class_EditorDebuggerPlugin_method_get_session:

.. rst-class:: classref-method

:ref:`EditorDebuggerSession<class_EditorDebuggerSession>` **get_session** **(** :ref:`int<class_int>` id **)**

Returns the :ref:`EditorDebuggerSession<class_EditorDebuggerSession>` with the given ``id``.

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

----

.. _class_EditorDebuggerPlugin_method_get_sessions:

.. rst-class:: classref-method

:ref:`Array<class_Array>` **get_sessions** **(** **)**

Returns an array of :ref:`EditorDebuggerSession<class_EditorDebuggerSession>` currently available to this debugger plugin.

Note: Not sessions in the array may be inactive, check their state via :ref:`EditorDebuggerSession.is_active<class_EditorDebuggerSession_method_is_active>`

.. |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.)`
.. |constructor| replace:: :abbr:`constructor (This method is used to construct a type.)`
.. |static| replace:: :abbr:`static (This method doesn't need an instance to be called, so it can be called directly using the class name.)`
.. |operator| replace:: :abbr:`operator (This method describes a valid operator to use with this type as left-hand operand.)`
