org.codehaus.jackson.map.KeyDeserializer
Abstract class that defines API used for deserializing Json content field names into Java Map keys. These deserializers are only used if the Map key class is not String or Object.

        // Ok: must point to START_OBJECT
        if (jp.getCurrentToken() != JsonToken.START_OBJECT) {
            throw ctxt.mappingException(_mapClass);
        }


        KeyDeserializer keyDes = _keyDeserializer;
        JsonDeserializer<Object> valueDes = _valueDeserializer;


        while ((jp.nextToken()) != JsonToken.END_OBJECT) {
            // Must point to field name
            String fieldName = jp.getCurrentName();
            Object key = (keyDes == null) ? fieldName : keyDes.deserializeKey(fieldName, ctxt);
            // And then the value...
            JsonToken t = jp.nextToken();
            // Note: must handle null explicitly here; value deserializers won't
            Object value = (t == JsonToken.VALUE_NULL) ? null : valueDes.deserialize(jp, ctxt);
