Interface SiteManager

All Known Implementing Classes:

AbstractSiteManager, TopicMapSiteManager

public interface SiteManager

A site structure management component.

A site manager has a dependence relation, which is always applied to documents of a single language. This means a document may not require a document of another language. Dependence on a set of resources must be a strict partial order < :

• irreflexive: d < d does not hold for any resource d
• antisymmetric: d < e and e < d implies d=e
• transitive: d < e and e < f implies d < f
