public interface E
Interface of an edge defined by a source, a target and an type.
Otherwise stated, an edge can be viewed as a statement subject, predicate,
object considering that all elements are URIs.
Note that edges are not expected to be modifiable i.e. their source, target
and type must be final. Therefore no setters must be specified for the
source, the target and the predicate of the edge. Moreover the aforementioned
elements must not be null.
