Method
JavaScriptCoreClassadd_methodv
Declaration [src]
void
jsc_class_add_methodv (
JSCClass* jsc_class,
const char* name,
GCallback callback,
gpointer user_data,
GDestroyNotify destroy_notify,
GType return_type,
guint n_parameters,
GType* parameter_types
)
Description [src]
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.
This method is renamed to jsc_class_add_method() in language bindings
