NetBeansTV: Top 10 NetBeans APIs (Part 7)
The 2nd part of the revision, this time covering the FileSystem API, the Nodes API, and the Explorer & Property Sheet API. You must have watched at least part 4 and part 5 before watching this screencast, because this screencast revises those.
NetBeans internally uses the concept of a virtual filesystem. FileSystem module provide APIs for accessing such virtual files as well as some support classes to make writing of custom vitual filesystems easier.
Nodes API gives you a generic model that is suitable for a number of different Swing components, instead of requiring you to rewrite the model when you switch between different UI components.
