                           ...);

Add a constructor to jsc_class . If name is NULL, the class name will be used. When new is used with the constructor or jsc_value_constructor_call() is called, callback is invoked receiving the parameters and user_data as the last parameter. When the constructor object is cleared in the JSCClass context, destroy_notify is called with user_data as parameter.

This function creates the constructor, which needs to be added to an object as a property to be able to use it. Use jsc_context_set_value() to make the constructor available in the global object.

Note that the value returned by callback is adopted by jsc_class , and the GDestroyNotify passed to jsc_context_register_class() is responsible for disposing of it.

Add a constructor to jsc_class . If name is NULL, the class name will be used. When new is used with the constructor or jsc_value_constructor_call() is called, callback is invoked receiving a GPtrArray of JSCValues as arguments and user_data as the last parameter. When the constructor object is cleared in the JSCClass context, destroy_notify is called with user_data as parameter.

This function creates the constructor, which needs to be added to an object as a property to be able to use it. Use jsc_context_set_value() to make the constructor available in the global object.

                      ...);

Add method with name to jsc_class . When the method is called by JavaScript or jsc_value_object_invoke_method(), callback is called receiving the class instance as first parameter, followed by the method parameters and then user_data as last parameter. When the method is cleared in the JSCClass context, destroy_notify is called with user_data as parameter.

Note that the value returned by callback must be transfer full. In case of non-refcounted boxed types, you should use G_TYPE_POINTER instead of the actual boxed GType to ensure that the instance owned by JSCClass is used. If you really want to return a new copy of the boxed type, use JSC_TYPE_VALUE and return a JSCValue created with jsc_value_new_object() that receives the copy as the instance parameter.
