- :ref:`bool<class_bool>` **can_instance** **(** :ref:`String<class_String>` class **)** const

Returns ``true`` if you can instance objects from the specified ``class``, ``false`` in other case.

.. _class_ClassDB_method_class_exists:

- :ref:`bool<class_bool>` **class_exists** **(** :ref:`String<class_String>` class **)** const

Returns whether the specified ``class`` is available or not.

.. _class_ClassDB_method_class_get_category:

- :ref:`String<class_String>` **class_get_category** **(** :ref:`String<class_String>` class **)** const

Returns a category associated with the class for use in documentation and the Asset Library. Debug mode required.

.. _class_ClassDB_method_class_get_integer_constant:

- :ref:`int<class_int>` **class_get_integer_constant** **(** :ref:`String<class_String>` class, :ref:`String<class_String>` name **)** const

Returns the value of the integer constant ``name`` of ``class`` or its ancestry. Always returns 0 when the constant could not be found.

.. _class_ClassDB_method_class_get_integer_constant_list:

- :ref:`PoolStringArray<class_PoolStringArray>` **class_get_integer_constant_list** **(** :ref:`String<class_String>` class, :ref:`bool<class_bool>` no_inheritance=false **)** const

Returns an array with the names all the integer constants of ``class`` or its ancestry.

.. _class_ClassDB_method_class_get_method_list:

- :ref:`Array<class_Array>` **class_get_method_list** **(** :ref:`String<class_String>` class, :ref:`bool<class_bool>` no_inheritance=false **)** const

Returns an array with all the methods of ``class`` or its ancestry if ``no_inheritance`` is ``false``. Every element of the array is a :ref:`Dictionary<class_Dictionary>` with the following keys: ``args``, ``default_args``, ``flags``, ``id``, ``name``, ``return: (class_name, hint, hint_string, name, type, usage)``.

.. _class_ClassDB_method_class_get_property:

- :ref:`Variant<class_Variant>` **class_get_property** **(** :ref:`Object<class_Object>` object, :ref:`String<class_String>` property **)** const

Returns the value of ``property`` of ``class`` or its ancestry.

.. _class_ClassDB_method_class_get_property_list:

- :ref:`Array<class_Array>` **class_get_property_list** **(** :ref:`String<class_String>` class, :ref:`bool<class_bool>` no_inheritance=false **)** const

Returns an array with all the properties of ``class`` or its ancestry if ``no_inheritance`` is ``false``.

.. _class_ClassDB_method_class_get_signal:

- :ref:`Dictionary<class_Dictionary>` **class_get_signal** **(** :ref:`String<class_String>` class, :ref:`String<class_String>` signal **)** const

Returns the ``signal`` data of ``class`` or its ancestry. The returned value is a :ref:`Dictionary<class_Dictionary>` with the following keys: ``args``, ``default_args``, ``flags``, ``id``, ``name``, ``return: (class_name, hint, hint_string, name, type, usage)``.

.. _class_ClassDB_method_class_get_signal_list:

- :ref:`Array<class_Array>` **class_get_signal_list** **(** :ref:`String<class_String>` class, :ref:`bool<class_bool>` no_inheritance=false **)** const

Returns an array with all the signals of ``class`` or its ancestry if ``no_inheritance`` is ``false``. Every element of the array is a :ref:`Dictionary<class_Dictionary>` as described in :ref:`class_get_signal<class_ClassDB_method_class_get_signal>`.

.. _class_ClassDB_method_class_has_integer_constant:
