[jboss-jira] [JBoss JIRA] Commented: (JGRP-1141) RspList: use generics
[
https://issues.jboss.org/browse/JGRP-1141?page=com.atlassian.jira.plugin....
]
Bela Ban commented on JGRP-1141:
--------------------------------
The issue is that if we use generics, callers have to change
RspList rsps=disp.callXXX();
to
RspList<Object> rsps=...; // or the real type of the return value
The problem is that this doesn't add to type safety at compile time, e.g.
If we define RspList<Integer> rsps=disp.callRemoteMethods(...);
and get back a list of Strings, then
Integer val=rsps.getFirst(); // this will throw a ClassCastException
RspList: use generics
