| === I have a folder full of .instance files. How do I get any/all of the object instances? |
| |
| Often registries of objects are created by placing files with the extension `.instance` into some folder in the link:DevFaqSystemFilesystem.asciidoc[system filesystem]. The task, then, is to turn a folder full of files into a collection of objects, and make sure we only get objects of the type we are interested in. In NetBeans 6 it is very simple to do that: |
| |
| [source,java] |
| ---- |
| |
| Lookup myObjects = Lookups.forPath ("path/to/folder/in/sysfs"); |
| Collection <? extends MyType> c = myObjects.lookupAll(MyType.class); |
| |
| ---- |
| |
| (note the separator is always / with NetBeans filesystems). |
| |
| If you have a single `.instance` file and need to get an object for that, link:DevFaqFindInstance.asciidoc[see this FAQ entry]. |
