Help with hw 1:
http://www.ccs.neu.edu/home/lieber/com1205/f02/hw/1/

Execute the Unix command

fgrep "_trv(" *.java

in the graph/gen subdirectory.

We get:

Adj.java: void allInh_Cd_graph_trv(CountingVisitor c) {
Adj.java: vertex.allInh_Cd_graph_trv(c);
Adj.java: ns.allInh_Cd_graph_trv(c);
Adj_list.java: void allInh_Cd_graph_trv(CountingVisitor c) { }
Alternat.java: void allInh_Cd_graph_trv(CountingVisitor c) {
Alternat.java: first.allInh_Cd_graph_trv(c);
Alternat.java: second.allInh_Cd_graph_trv(c);
Any_vertex.java: void allInh_Cd_graph_trv(CountingVisitor c) { }
Any_vertex_list.java: void allInh_Cd_graph_trv(CountingVisitor c) { }
Cd_graph.java: allInh_Cd_graph_trv(c);
Cd_graph.java: void allInh_Cd_graph_trv(CountingVisitor c) {
Cd_graph.java: first.allInh_Cd_graph_trv(c);
Cd_graph.java: rest.allInh_Cd_graph_trv(c);
Construct.java: void allInh_Cd_graph_trv(CountingVisitor c) {
Construct.java: c_ns.allInh_Cd_graph_trv(c);
Empty.java: void allInh_Cd_graph_trv(CountingVisitor c) { }
Empty_cd_graph.java: void allInh_Cd_graph_trv(CountingVisitor c) { }
Labeled_vertex.java: void allInh_Cd_graph_trv(CountingVisitor c) {
Labeled_vertex.java: class_name.allInh_Cd_graph_trv(c);
Nany_vertex_list.java: void allInh_Cd_graph_trv(CountingVisitor c) {
Nany_vertex_list.java: first.allInh_Cd_graph_trv(c);
Nany_vertex_list.java: rest.allInh_Cd_graph_trv(c);
Neighbors.java: void allInh_Cd_graph_trv(CountingVisitor c) { }
Syntax_vertex.java: void allInh_Cd_graph_trv(CountingVisitor c) { }
Vertex.java: void allInh_Cd_graph_trv(CountingVisitor c) {

How can you succinctly describe this traversal program as
a traversal specification?
