Question

Is it possible to draw a self referencial association at one specific class in MetaUML?
Suppose i have the Class item:

Class.Item("Item")()();

and want to add a self refencing assocaition to itself using:

 clink(association)(Item,Item);

But this won’t work (nothing is displayed). What is the correct way to do this?

Answer 1

input metauml;
beginfig(1);
    Class.A("Tree")()();
    drawObjects(A);
    link(aggregationUni)(A.e -- A.e+(30,0) -- (A.right+30,A.bottom-40) -- A.s+(0,-40) -- A.s);
endfig;
end

For this particular scenario, you need to create the link path by hand.

More common types of link paths can be created with the macros described in the manual, section 9 – Drawing Paths.
