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 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
