| === I have a .instance file. How do I get an actual object instance? |
| |
| Using `InstanceCookie` (note that if you have an entire folder of `.instance` files, there's a link:DevFaqFolderOfInstances.html[more efficient way ] to get all of them): |
| |
| [source,java] |
| ---- |
| |
| DataObject dob = DataObject.find (theDotInstanceFileObject); |
| InstanceCookie ck = dob.getLookup().lookup(InstanceCookie.class); |
| MyObject obj = (MyObject) ck.instanceCreate(); |
| |
| ---- |
| |
| (you can and should call `ck.instanceClass()` to ensure the type cast is correct ahead of time) |
| |
| ==== Alternative: |
| |
| [source,java] |
| ---- |
| |
| T obj=FileUtil.getConfigObject("Actions/Window/org-foo-B.instance", T.class) |
| |
| //for example: |
| Action action=FileUtil.getConfigObject("Actions/Window/org-netbeans-core-windows-actions-ResetWindowsAction.instance", Action.class) |
| |
