Subject [jira] [Updated] (WHIRR-724) Add a listener to calls to ClusterActionHandlerSupport.beforeAction and .afterAction
Date Tue, 07 May 2013 17:05:15 GMT

     [ https://issues.apache.org/jira/browse/WHIRR-724?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Andrew Bayer updated WHIRR-724:
-------------------------------

    Attachment: WHIRR-724.patch

This patch adds a ClusterActionHandlerListener class, which has beforeEvent and afterEvent
methods which get called from ClusterActionHandlerSupport's beforeAction and afterAction methods,
respectively. The listener is specified in the ClusterSpec, and defaults to a no-op.

> When using Whirr as a library, rather than as a command-line tool directly, it'd be very
handy to be able to have a listener class called when handlers' events are called, for logging/monitoring/etc.
