public class RELATIONNode
extends DrawableX_Node
A RELATIONSHIP class. The contents of RELATION are of the form: 

  GRAPHNODE:203-227
  MOL:3
or ARRAY for many-many relationships.  There must be exactly one each of END1
and END2.  An attribute DIRECTED=YES signifies a directed link from END1 to 
END2

Constructor Index

o RELATIONNode(SGMLTree, Vector, Vector, boolean)
construct from two FullAddressVectors, one for each end
o RELATIONNode(String, SGMLTree)
default constructor; this has no 'contents'

Method Index

o createAndAdd(SGMLTree, int, Vector, Vector, boolean)
o debug()
for debug
o display()
displays the nodes.
o display(Graphics)
no routine yet to display the relationships...
o displayRELATIONTargets(FullAddress)
display all RELATION
o getAllRELATIONNodes(SGMLTree)
get all RELATION in the document
o getFullAddress(FullAddress)
get all the addresses corresponding to the END(n) values where 'fa' matches the other END value.
o getXARR()
get the ARRAY Objects
o getXVAR()
get the XVAR Objects
o mayContain(SGMLNode)
can this node contain others.
o process()
complex objects may require processing; override this.
o showHelp()
display Help

Constructors

o RELATIONNode 
  public RELATIONNode(String giName,
                      SGMLTree tree)
default constructor; this has no 'contents'
o RELATIONNode 
  public RELATIONNode(SGMLTree tree,
                      Vector fav0,
                      Vector fav1,
                      boolean bidirectional)
construct from two FullAddressVectors, one for each end

Methods

o createAndAdd 
  public static int createAndAdd(SGMLTree tree,
                                 int parentIndex,
                                 Vector fav0,

                                 boolean bidirectional)
o showHelp 
  public void showHelp()
display Help
Overrides:
showHelp in class DrawableX_Node
o mayContain 
  public boolean mayContain(SGMLNode n)
can this node contain others.
Overrides:
mayContain in class DrawableX_Node
o process 
  public void process()
complex objects may require processing; override this.
Overrides:
process in class DrawableSGMLNode
o getXVAR 
  public XVARNode[] getXVAR()
get the XVAR Objects
o getXARR 
  public ARRAYNode[] getXARR()
get the ARRAY Objects
o display 
  public void display()
displays the nodes. Doesn't yet clear subaddresses in nodes before it starts...
Overrides:
display in class DrawableSGMLNode
o display 
  public void display(Graphics g)
no routine yet to display the relationships...
Overrides:
display in class DrawableX_Node
o getAllRELATIONNodes 
  public static RELATIONNode[] getAllRELATIONNodes(SGMLTree tree)
get all RELATION in the document
o displayRELATIONTargets 
  public static void displayRELATIONTargets(FullAddress fa)
display all RELATION
o getFullAddress 
  public FullAddress[] getFullAddress(FullAddress fa)
get all the addresses corresponding to the END(n) values where 'fa' matches the other END value. If none found, return null. If BIDIRECTIONAL=NO, only END1 values are searched.
o debug 
  public void debug()
for debug
Overrides:
debug in class DrawableX_Node
