When I debug this method, I can clearly see that currentNode = Workstation, so I am puzzled as to why I'm still entering into the "Node" buffer print, rather than the "Workstation" buffer print. Shouldn't polymorphism handle this for me?:
part of Node Class
public void printToBufferAsHTML(Network network, StringBuffer buf) {
buf.append("<HTML>\n<HEAD>\n<TITLE>LAN Simulation</TITLE>\n</HEAD>\n<BODY>\n<H1>LAN SIMULATION</H1>");
Node currentNode = this;
buf.append("\n\n<UL>");
do {
buf.append("\n\t<LI> ");
if (isValidNode(currentNode))
currentNode.printNodeToBufferAsHTML(buf, currentNode);
else
buf.append("(Unexpected)");
buf.append(" </LI>");
currentNode = currentNode.nextNode;
} while (network.notCompleteCycle(currentNode));
buf.append("\n\t<LI>...</LI>\n</UL>\n\n</BODY>\n</HTML>\n");
}
private void printNodeToBufferAsHTML(StringBuffer buf, Node currentNode) {
buf.append("Node ");
buf.append(currentNode.name);
buf.append(" [Node]");
}public class Workstation extends Node{
public Workstation(String _name) {
super(_name);
}
public Workstation(String _name, Node _nextNode) {
super(_name, _nextNode);
}
public void printNodeToBufferAsHTML(StringBuffer buf, Node currentNode) {
buf.append("Workstation ");
buf.append(currentNode.name);
buf.append(" [Workstation]");
}
}
