.. _class_ResourceFormatSaver:

ResourceFormatSaver
===================

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

Saves a specific resource type to a file.

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

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

The engine can save resources when you do it from the editor, or when you use the :ref:`ResourceSaver<class_ResourceSaver>` singleton. This is accomplished thanks to multiple **ResourceFormatSaver**\ s, each handling its own format and called automatically by the engine.

By default, Godot saves resources as ``.tres`` (text-based), ``.res`` (binary) or another built-in format, but you can choose to create your own format by extending this class. Be sure to respect the documented return types and values. You should give it a global class name with ``class_name`` for it to be registered. Like built-in ResourceFormatSavers, it will be called automatically when saving resources of its recognized type(s). You may also implement a :ref:`ResourceFormatLoader<class_ResourceFormatLoader>`.

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

.. _class_ResourceFormatSaver_private_method__get_recognized_extensions:

.. rst-class:: classref-method

:ref:`PackedStringArray<class_PackedStringArray>` **_get_recognized_extensions**\ (\ resource\: :ref:`Resource<class_Resource>`\ ) |virtual| |const| :ref:`🔗<class_ResourceFormatSaver_private_method__get_recognized_extensions>`

Returns the list of extensions available for saving the resource object, provided it is recognized (see :ref:`_recognize()<class_ResourceFormatSaver_private_method__recognize>`).

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

----

.. _class_ResourceFormatSaver_private_method__recognize:

.. rst-class:: classref-method

:ref:`bool<class_bool>` **_recognize**\ (\ resource\: :ref:`Resource<class_Resource>`\ ) |virtual| |const| :ref:`🔗<class_ResourceFormatSaver_private_method__recognize>`

Returns whether the given resource object can be saved by this saver.

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

----

.. _class_ResourceFormatSaver_private_method__recognize_path:

.. rst-class:: classref-method

:ref:`bool<class_bool>` **_recognize_path**\ (\ resource\: :ref:`Resource<class_Resource>`, path\: :ref:`String<class_String>`\ ) |virtual| |const| :ref:`🔗<class_ResourceFormatSaver_private_method__recognize_path>`

Returns ``true`` if this saver handles a given save path and ``false`` otherwise.

If this method is not implemented, the default behavior returns whether the path's extension is within the ones provided by :ref:`_get_recognized_extensions()<class_ResourceFormatSaver_private_method__get_recognized_extensions>`.

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

----

.. _class_ResourceFormatSaver_private_method__save:

.. rst-class:: classref-method

:ref:`Error<enum_@GlobalScope_Error>` **_save**\ (\ resource\: :ref:`Resource<class_Resource>`, path\: :ref:`String<class_String>`, flags\: :ref:`int<class_int>`\ ) |virtual| :ref:`🔗<class_ResourceFormatSaver_private_method__save>`

Saves the given resource object to a file at the target ``path``. ``flags`` is a bitmask composed with :ref:`SaverFlags<enum_ResourceSaver_SaverFlags>` constants.

Returns :ref:`@GlobalScope.OK<class_@GlobalScope_constant_OK>` on success, or an :ref:`Error<enum_@GlobalScope_Error>` constant in case of failure.

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

----

.. _class_ResourceFormatSaver_private_method__set_uid:

.. rst-class:: classref-method

:ref:`Error<enum_@GlobalScope_Error>` **_set_uid**\ (\ path\: :ref:`String<class_String>`, uid\: :ref:`int<class_int>`\ ) |virtual| :ref:`🔗<class_ResourceFormatSaver_private_method__set_uid>`

Sets a new UID for the resource at the given ``path``. Returns :ref:`@GlobalScope.OK<class_@GlobalScope_constant_OK>` on success, or an :ref:`Error<enum_@GlobalScope_Error>` constant in case of failure.

.. |virtual| replace:: :abbr:`virtual (This method should typically be overridden by the user to have any effect.)`
.. |required| replace:: :abbr:`required (This method is required to be overridden when extending its base class.)`
.. |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.)`
.. |bitfield| replace:: :abbr:`BitField (This value is an integer composed as a bitmask of the following flags.)`
.. |void| replace:: :abbr:`void (No return value.)`
