| === Where is `TopManager`? I'm trying to do the examples from the O'Reilly book |
| |
| The O'Reilly book is old (written between 2001 and 2002) - the chapters on architectural background will still work, but many of the examples won't. |
| |
| The generation of NB it was written for is from before Lookup (see link:DevFaqLookup.asciidoc[DevFaqLookup]) was in use. `TopManager` was a class with a bunch of static methods for getting service objects. |
| It is now gone. |
| |
| For pretty much everything available via `TopManager`, simply take the class you were looking for and try `SomeClass.getDefault()` - that's typically the modern way to do this sort of thing. `TopManager` caused a tangle of interdependencies between different APIs that it was very desirable to remove. |
| |
| If you were calling `TopManager.getDefault().getPlaces().nodes().projectDesktop()` in a NetBeans 3.x based application, there is no direct equivalent in NB 4.0 and later. Rather, there is a rich set of project-related APIs which can be used for various purposes. As a rule, there is no 1-to-1 conversion from the above idiom to NB 4.0+; the affected O'Reilly examples would need to be rewritten to make sense today. |
