Note that the value returned by getter must be fully transferred. In case of boxed types, you could 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 instance parameter.

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 the function parameters 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.
