Marshall Schor commented on UIMA-5207: -------------------------------------- Semantic versioning says this change (adding the Iterable interface and the iterator() method) to these classes is a non-compatible change. I tried reading the Java Language Spec and asking the internet - these sources seem to say that this change is compatible, since it is only adding a new method. Here's the choices I see: 1) don't implement this improvement for 2.10.0, but only for 3.0.0 2) implement it for 2.10.0, but disable the semver checking for this release. There is a risk that (2) would produce binaries that would not "link" with pre-existing code. This might be tested by someone during our release process; we could roll back the release candidate if it failed. Can someone say more precisely why the semver enforcement flags this as non-compatible? Here's a sample of the messages semver is producing: Class org.apache.uima.jcas.cas.FSArray Added Method iterator, sig ()Ljava/util/Iterator<Lorg/apache/uima/cas/FeatureStructure;>;, desc ()Ljava/util/Iterator;, access public Changed Class , access Class org.apache.uima.jcas.cas.FSList Changed Class , access Added Method iterator, sig ()Ljava/util/Iterator<Lorg/apache/uima/jcas/cas/TOP;>;, desc ()Ljava/util/Iterator;, access public > make FSArray/List, StringArray/list iterable > -------------------------------------------- > > Key: UIMA-5207 > URL: https://issues.apache.org/jira/browse/UIMA-5207 > Project: UIMA > Issue Type: Improvement > Components: Core Java Framework > Affects Versions: 2.9.0SDK > Reporter: Marshall Schor > Assignee: Marshall Schor > Priority: Minor > Fix For: 3.0.0SDKexp, 2.10.0SDK > > > The common collection-style Feature Structures in UIMA could implement > iterable, to enable writing for loops over them.
