      • adapt

        public PyObject adapt​(java.lang.Object o)
        Attempts to adapt o using the preClass, class and postClass adapters. First each of the preClass adapters is asked in the order of addition if they can adapt o. If so, they adapt it. Otherwise, if o.getClass() is equal to one of the classes from the added ClassAdapters, that class adapter is used. Finally, each of the post class adapters are asked in turn if they can adapt o. If so, that adapter handles it. If none can, null is returned.
