[jboss-jira] [JBoss JIRA] (WFLY-5175) Add lamba support for CommandDispatcher commands.

[Paul Ferraro (JIRA)]

     [ https://issues.jboss.org/browse/WFLY-5175?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Paul Ferraro closed WFLY-5175.
------------------------------
    Resolution: Rejected


On second thought - the Command interface only has a single method, thus already supports lambda expressions!  And because Command extends Serializable, the resulting lambda expression will serialize just fine.

> Currently, one needs to create a Command object for each command to be executed via a CommandDispatcher. Now that WF is on Java 8, we should add support for specifying simple commands as lambdas.
> e.g.
> dispatcher.executeOnCluster(context -> context.doSomething());
> Of course, there is the matter of serializability.  I'm hoping this is a simple as making the Command interface (or some sub-interface) a @FunctionalInterface - and given that this already extends Serializable, we should be ok.  This should just be a matter of experimentation.
