Public Constructors

public RootCategory (Level level)

The root category names itself as "root". However, the root category cannot be retrieved by name.

Public Methods

public final Level getChainedLevel ()

Return the assigned level value without walking the category hierarchy.

public final void setLevel (Level level)

Setting a null value to the level of the root category may have catastrophic results. We prevent this here.
