-------------------------------------
Resolution: Done
RESOLVED
- Methods queryInterface, getSupportedInterfaces and some related have been created in
org.jboss.tools.vpe.xulrunner.util.XPCOM .
- All references to org.mozilla.interfaces.nsISupports.queryInterface(String) have been
replaced by the references to the new method.
- JUnit for new org.jboss.tools.vpe.xulrunner.util.XPCOM methods has been created.
- JUnit tests for org.jboss.tools.vpe.xulrunner plug-in have been refactored.
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: Yahor Radtsevich
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)
