Hello struts-dev,
This evening I end up druft of ServicesServlet - extended version of
ActionServlet with support of pluggable services (extensions in old
terms). I puzzle over architectural question about ServicesServlet
and may be anybody can suggest me right way...
ServiceServlet work on idea - developer can register unlimited
number of services in struts-config, each service is a java class
based on Service interface, each service can be subscribed to any
processing point, such as - init, destroy, initDigester,
processPreprocess, processPopulateBefore, processPopulateAfter,
processValidateBefore, processValidateAfter. ServiceServlet iterate
via list of subscriptions at every processing point and call
appropriate method from service.
My question is - what way is the best to serve processing points
listed above? Now I create FastArrayList instances for every
subscription list and all manipulations with subscriptions
(register, get iterator via subscriptions, drop, etc.) are made with
help of separate method -
registerInitMember( Service service, int order ) {}
regisetrInitDigesterMember( Service service, int order ) {}
....
May be such solution would be more flexible? -
registerMember( Service service, int order, String pointName ) {
//find ArrayList of subscriptions for such pointName
//register service at ArrayList
}
Hard coded solution is more reliable, but time consume and not
flexible. But more flexible solution, with search for appropriate
subscription, is slow for my mind. What way is the best?
