public final class RootCategory
extends Logger

RootCategory sits at the top of the category hierachy. It is a regular category except that it provides several guarantees.

First, it cannot be assigned a null priority. Second, since root category cannot have a parent, the getChainedLevel() method always returns the value of the level field without walking the hierarchy.
