public PyObject adapt(java.lang.Object o)

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.- Specified by:
