slib.sglib.model.graph.elements
Interface E


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. there 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 source, the target and the predicate must not be null.
