[jira] [Updated] (ZOOKEEPER-3523) Replace dummy watcher with a
unified singleton
[ https://issues.apache.org/jira/browse/ZOOKEEPER-3523?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
TisonKun updated ZOOKEEPER-3523:
--------------------------------
Description: Currently we have many anonymous subclasses of {{Watch}} all of which is just event -> { }. We can reduce many subclasses in inherit tree by add a {{DUMMY_WATCHER}} in {{Watcher}} interface and replace all of those usages. (was: Currently we have many anonymous subclasses of {{Watch}} all of which is just {{event -> \{ }}}. We can reduce many subclasses in inherit tree by add a {{DUMMY_WATCHER}} in {{Watcher}} interface and replace all of those usages.)
