Value.function_variadic
Description:
public Value.function_variadic (Context context, string? name, Callback callback, void* user_data, DestroyNotify? destroy_notify, Type return_type)
Create a function in context
.
If name
is null an anonymous function will be created. When the function is called by
JavaScript or jsc_value_function_call
, callback
is called receiving an
GenericArray of Value
<!-- -->s with the arguments and then user_data
as last parameter. When the function is cleared in context
,
destroy_notify
is called with user_data
as parameter.
Note that the value returned by callback
must be fully transferred. In case of boxed types, you could use
g_type_pointer instead of the actual boxed Type to
ensure that the instance owned by Class is used. If you really want to return
a new copy of the boxed type, use JSC_TYPE_VALUE
and return a Value
created with Value.object that receives the copy
as instance parameter.
