Opendelight Libraries

Opendelight Libraries are classes developed or distributed as the part of Opendelight framework to facilitate additional objects to develop your application. These classes are available in /lib directory, and are autoloaded when instantiated (i.e., you do not need to include these class files in the application when you want to instantiate them). The names of these classes usually start with Delight_.
