[jboss-jira] [JBoss JIRA] Commented: (JBMICROCONT-165) Add support for Install items

[Adrian Brock (JIRA)]

Adrian Brock commented on JBMICROCONT-165:
------------------------------------------

This requires changes to the DependecyInfo to a list of InstallItems
not just DependencyItems.

The install items are not necessarily required for the service to start
but they will be updated as the services of that type come and go.

The Microcontainer controller already tracks implementing classes
for the contextual injections, so this code needs updating
to also process the InstallItems.

> We already support contextual dependency injection
> (injected based on class)
> @Inject
> public void setSomething(X x);
> and installation into "repositories"
> <bean name="Queue1">
>    <install bean="JMSBroker" method="addQueue"/>
> </bean>
> There should be additional support for more dynamic injection/installation.
> In annotations the three new features are:
> 1) The injection is dynamic
> - the service will start even if the dependency is not satisifed
> - the service might get the injection later when it is available
> @Inject(optional=true)
> public void setSomething(X x);
> 2) Installation of "services" by type
> - Inject all implementors of a particular class
> - Keep reinjecting as implementors come and go
> - The cardinality specifies the minimum number
> that must exist for the service to start
> @Install(cardinality=0)
> public void setSomethings(Collection<X> x)
> 3) Like (2) but with add/remove methods
> @Install(cardinality=0)
> public void addSomething(X x)
> @Uninstall
> public void removeSomething(X x)
