Class Concept

java.lang.Object
org.aksw.jenax.sparql.fragment.impl.Concept
All Implemented Interfaces:
Fragment, Fragment1, HasElement

    • TOP

      public static final Concept TOP
      There are several ways how top/bottom could be represented. Clients attempting to indicate top/bottom should attempt to ensure reference equality with these constants
