Stefan Egli closed SLING-4685. ------------------------------ > Introduce generic discovery.commons.ViewStateManager sharable for impls > ----------------------------------------------------------------------- > > Key: SLING-4685 > URL: https://issues.apache.org/jira/browse/SLING-4685 > Project: Sling > Issue Type: Improvement > Components: Extensions > Reporter: Stefan Egli > Assignee: Stefan Egli > Fix For: Discovery Commons 1.0.0 > > Attachments: SLING-4685.patch > > > With multiple discovery implementations existing/upcoming it starts to become > valuable to share code that can be shared. And with the introduction of > discovery.commons we have a nice place for this. > As a first thing, I propose to introduce a discovery.commons.ViewStateManager > (the name can be changed if wished of course): this one is capable of > managing a number of TopologyChangeListeners, can be in deactivated/activated > state and can react on {{handleChanging}} and {{handleNewView}} events and > translates all of those to correct events that it sends to the registered > listeners accordingly. > This also takes into account the fact that the TOPOLOGY_INIT should be sent > only when the first valid view is available - which is flagged to > ViewStateManager via {{handleNewView}}. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
