Method

JavaScriptCoreClassadd_constructor

Declaration [src]

JSCValue*
jsc_class_add_constructor (
  JSCClass* jsc_class,
  const char* name,
  GCallback callback,
  gpointer user_data,
  GDestroyNotify destroy_notify,
  GType return_type,
  guint n_params,
  ...
)

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 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.

This method is not directly available to language bindings.

The implementation of this method is provided by jsc_class_add_constructorv() in language bindings
