: So for a given instance of a handler it will only be called once during the : lifetime of that handler?
correct (unless there is a bug somewhere) : Also, when the core is passed in as part of inform() is it guaranteed to be : ready to go? (ie I can start feeding content at this point?) Right, that's the point of the interface: way back in the day we had people writting plugins that were trying to use SolrCore from their init() methods and the SolrCore wasn't fully initialized yet (didn't have DirectUpdateHandler yet, didn't have all of hte RequestHandler's initialized, didn't have an openSearcher, etc...) the inform(SolrCore) method is called after the SolrCore is initialized, and all plugins hanging off of it have been init()ed ... you can still get into trouble if you write FooA.inform(SolrCore) such that it asks the SolrCore for for a pointer to some FooB plugin and expect that FooB's infomr(SolrCore) method has already been called -- because there is no garunteed order -- but the basic functionality and basic plugin initialization has all been done at that point. -Hoss
