Create generic queryInterface method ------------------------------------ Key: JBIDE-6393 URL: https://jira.jboss.org/browse/JBIDE-6393 Project: Tools (JBoss Tools) Issue Type: Task Components: Visual Page Editor core Affects Versions: 3.2.0.M1 Reporter: Yahor Radtsevich Assignee: Maxim Areshkau Fix For: 3.2.0.M1 Our current approach to cast XULRunner types is to use nsISupports.queryInterface(String). Typical code using this method: nsIDOMMouseEvent mouseEvent = (nsIDOMMouseEvent) event .queryInterface(nsIDOMMouseEvent.NS_IDOMMOUSEEVENT_IID); These long boilerplate calls are always look the same and they are far from object-oriented approach. An object-oriented generic method is needed. It should look like the following: <T extends nsISupports> T queryInterface(nsISupports object, Class<T> type) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
