Class Description

RooGraphEdge:                                                              
                                                                           
The edge class is a subset of the node class and an edge can only be made  
if there are two nodes to connect it to. It is used to show how the nodes  
depend on each other, and to help display the topology of the graph.  They 
are also necessary for finding the graph lenght for the springs.

RooGraphEdge()

Default constructor for an edge

RooGraphEdge(RooGraphNode *n1, RooGraphNode *n2)

Edge standard constructor with default edge type

RooGraphEdge(RooGraphNode *n1, RooGraphNode *n2, TString es)

Edge standard constructor

void print()

prints the names of the nodes the edge is connected to to the screen

void read(ifstream &file)

gets the information needed to draw an edge from a file of a special format

void Set1stNode(RooGraphNode *n1)

sets the first node for the edge

void Set2ndNode(RooGraphNode *n2)

sets the second node for the edge

void Connect()

draw the edge to the canvas in the form of either a line, or arrow

void Connect(int color)

draws the egde to the canvas with the given color

void Connect(RooGraphNode *n1, RooGraphNode *n2)

draws the edge to the screen with the given imput nodes

double GetInitialDistance()

Returns the length of the edge

TObject * GetType(TList *padlist)

returns the object that represents the edge on the canvas

double GetX1()

returns the value for x1

double GetY1()

returns the value for y1

double GetX2()

returns the value for x2

double GetY2()

returns the value for y2

void SwitchNodes()

switches the nodes of the edge

RooGraphEdge()

void SetType(TString es)

const char* Get1stNode()

const char* Get2ndNode()

TString GetStyle()
