Builds the string that takes the NFA to the state that shows EDA.

Parameters:

m - The graph reperesenting the NFA.

finish - The state that shows EDA.

Returns:

The string built.

buildStringFromEdges

public static String buildStringFromEdges(LinkedList<NFAEdge> edges)

This function loops through a list of edges and build a string of all edges representing a symbol transition.

Parameters:

edges - The list of edges.

Returns:

The string built.

buildPumpIntersect

public static String buildPumpIntersect(NFAGraph pcscc,
                                        NFAVertexND p,

Parameters:

pcscc - The scc in the product construction.

p - The state that shows EDA, to build the path from.

q - The state to build the path to.

Returns:

The string capable of exploiting the vulnerable regular expression.
