---------------------------------
Summary: Use wildcard in methods returning keys
Key: ISPN-7108
URL:
https://issues.jboss.org/browse/ISPN-7108
Project: Infinispan
Issue Type: Enhancement
Components: Core
Reporter: Radim Vansa
Assignee: Radim Vansa
When a command uses generics (that's the case of functional commands), it stores keys
in {{Collection<? extends K>}}. That does not work well with {{getAffectedKeys()}}
returning {{Set<Object>}} - besides Collection/Set the generic type also cannot
match (because returning {{Set<Object>}} means that you can theoretically insert any
{{Object}}). Changing that to wildcard deals with this and makes the collection
effectively read-only.
