public abstract class ExpansionNetwork
extends OTSNetwork

A Network consists of a set of links. Each link has, in its turn, a start node and an end node. An expandable network can be an (expanded) node as well. An example is shown below:

            |
     -------O--------
            |
 

can be expanded into:

            |
            A
           /|\
          / | \
    -----B--C--D-----
          \ | /
           \|/
            E
            |
 

Node O in the example is expanded into the subnetwork consisting of nodes A, B, C, D, and E, and links AB, AC, AD, BC, CD, BE, CE, and DE. It also means that when node expansion takes place, the links to node O have to be replaced. In the example below:

            X
            |
     Y------O-------Z
            |
            W
 

can be expanded into:

            X
            |
            A
           /|\
          / | \
    Y----B--C--D----Z
          \ | /
           \|/
            E
            |
            W
 

The node XO is replaced by XA, YO is replaced by YB, OZ is replaced by DZ, and OW is replaced by EW in the network. The reverse takes place when we do node collapse.
