Method

JavaScriptCoreClassadd_constructor_variadic

Declaration [src]

JSCValue*
jsc_class_add_constructor_variadic (
  JSCClass* jsc_class,
  const char* name,
  GCallback callback,
  gpointer user_data,
  GDestroyNotify destroy_notify,
  GType return_type
)

Description [src]

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.

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.

Parameters

`name`	`const char*`
	The constructor name or `NULL`.
	The argument can be `NULL`.
	The data is owned by the caller of the function.
	The value is a NUL terminated UTF-8 string.
`callback`	`GCallback`
	A `GCallback` to be called to create an instance of `jsc_class`.
`user_data`	`gpointer`
	User data to pass to `callback`.
	The argument can be `NULL`.
	The data is owned by the caller of the function.
`destroy_notify`	`GDestroyNotify`
	Destroy notifier for `user_data`.
	The argument can be `NULL`.
`return_type`	`GType`
	The `GType` of the constructor return value.

Return value

Returns:	`JSCValue`
	A `JSCValue` representing the class constructor.
	The caller of the method takes ownership of the data, and is responsible for freeing it.
