[jira] [Commented] (CURATOR-200) Proposal: Remove references to guava library from public APIs

["Mike Drob (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CURATOR-200?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14391626#comment-14391626 ] 

Mike Drob commented on CURATOR-200:
-----------------------------------

If we move up to Java 8, then we can replace Function and Predicate with the matching classes in {{java.util.function}}:
* https://docs.oracle.com/javase/8/docs/api/java/util/function/Function.html
* https://docs.oracle.com/javase/8/docs/api/java/util/function/Predicate.html

I have not found an easy alternative for TypeToken.

> The problem classes that I have found are:
> * curator-framework: org.apache.curator.framework.listen.ListenerContainer : method forEach takes a parameter of type com.google.common.base.Function
> * curator-framework: org.apache.curator.framework.api.transaction.CuratorTransactionResult : method ofTypeAndPath returns com.google.common.base.Predicate
> * curator-x-discovery-server: org.apache.curator.x.discovery.server.contexts.GenericDiscoveryContext : constructor takes param of type com.google.common.reflect.TypeToken
> * curator-x-discovery: org.apache.curator.x.discovery.InstanceFilter : inherits from com.google.common.base.Predicate
> {quote}
> In the ensuing discussion, it sounded like we'd need to get started on an implementation before we had enough information to determine whether the changes are too intrusive or not.
