Matt Drees commented on JBSEAM-2478:
------------------------------------
I don't think this would work for manager components like
org.jboss.seam.transaction.Transaction. E.g.,
(UserTransaction) Component.getInstance(Transaction.class);
Note that Transaction is not a UserTransaction.
Of course, I'd love a way to avoid that stupid cast. It might require a new method to
preserve backward-compatibility, unfortunately.
Maybe something like Component.getImplementation(UserTransaction.class).
Make Component.getInstance(class) typesafe

Key: JBSEAM-2478
URL:
http://jira.jboss.com/jira/browse/JBSEAM-2478
Project: JBoss Seam
Issue Type: Feature Request
Components: Core
Reporter: Christian Bauer
Priority: Minor
I don't know why these return Object, looks to me like we can make these generic and
avoid the cast:
public static Object getInstance(Class<?> clazz)
{
return getInstance(clazz, true);
}
public static Object getInstance(Class<?> clazz, boolean create)
{
return getInstance( getComponentName(clazz), create );
}
public static Object getInstance(Class<?> clazz, ScopeType scope)
{
return getInstance(clazz, scope, true);
}
public static Object getInstance(Class<?> clazz, ScopeType scope, boolean
create)
{
return getInstance( getComponentName(clazz), scope, create );
}
