org.jahia.services.categories.Category

Title: Category object

Description: This Category class is used to associate any objects within Jahia, be they Content Objects, Categories or others. It also provides static methods to manipulate Categories in the persistence back-end. This class is self-sufficient for most operations as it uses the category service back-end to perform most of it's work.
