[cdi-dev] [JBoss JIRA] (CDI-331) Clarify Instance.iterator()

Jozef Hartinger created CDI-331: ----------------------------------- Summary: Clarify Instance.iterator() Key: CDI-331 URL: https://issues.jboss.org/browse/CDI-331 Project: CDI Specification Issues Issue Type: Clarification Components: Resolution Affects Versions: 1.1.PRD Reporter: Jozef Hartinger Assignee: Pete Muir Fix For: 1.1.FD The specification currently says that: {quote} The iterator() method must: • Identify the set of beans that have the required type and required qualifiers and are eligible for injection into the class into which the parent Instance was injected, according to the rules of typesafe resolution, as defined in Section 5.2.1. {quote} The question that arises is whether the implementation should apply ambiguity resolution algorithm as defined in 5.2.2 or not. This is explicitly required for get() but is not required for iterator(). This causes the following inconsistency: Assume two classes Foo and Bar which both implement common interface Common. Bar is an enabled alternative. Assume further the following {noformat} @Inject @Any Instance<Common> instance {noformat} injection point. It is clear that instance.get() returns Bar. It is however not clear whether instance.iterator() iterates over: a) Bar b) Foo, Bar and whether instance.isAmbiguous() returns: a) true b) false -- This message is automatically generated by JIRA.
