public interface Node

A Node is an object that makes up a component of a mapping graph. Any implementation of a Node should describe three key things...

• The identifier for this Node (which is simply a string value which will be used to reference this Node when serialised as XML)
• The RDFResource used to describe the class of all objects encompassed by this node. This is the description of the class to select each entity from. This Node now represents the statement FOR ALL [identifier] IN [RDFResource]...
• A set of mappings for this Node. Each entity mapped to should be stored in this set, by means of the paired Nodes identifier. This can legally be an empty set.

Finally, all Nodes must implement the accept() method to enable a NodeVisitor to visit them. NodeVisitors are responsible for building the representation of the graph for the UI.

If you wish to implement Node, instead use AbstractNode which handles all the standard getter and setter methods, leaving only setRDFResource() to be implemented for each specific type of Node.
