[ http://issues.apache.org/jira/browse/HIVEMIND-87?page=comments#action_12417442 ]
Knut Wannheden commented on HIVEMIND-87: ---------------------------------------- This could be achieved by using a translator initializer. Then the syntax would be with a comma. E.g. <attribute name="object" translator="object,java.lang.Runnable"/> (Although I wonder if a '|' or ':' wouldn't be better as separator.) The object translator would have to work out how to perform the assignability check if given both a type in the initializer and a type as parameter to the translate() method. I.e. what to do if these are conflicting and which one is "stronger". > object translator: optionally, specify interface > ------------------------------------------------ > > Key: HIVEMIND-87 > URL: http://issues.apache.org/jira/browse/HIVEMIND-87 > Project: HiveMind > Type: New Feature > Components: framework > Reporter: Howard M.
