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
