Method Detail

wrap

public abstract EnhNode wrap(Node node,
                             EnhGraph eg)

Create a new EnhNode wrapping a Node in the context of an EnhGraph

Parameters:

node - The node to be wrapped

eg - The graph containing the node

Returns:

A new enhanced node which wraps node but presents the interface(s) that this factory encapsulates.

canWrap

public abstract boolean canWrap(Node node,
                                EnhGraph eg)

true iff wrapping (node, eg) would succeed.

Parameters:

node - the node to test for suitability

eg - the enhanced graph the node appears in

Returns:

true iff the node can represent our type in that graph
