    A spreadsheet is a DAG (Directed Acyclic Graph); a vertex V has an outgoing edge to a vertex W is vertex W has a component in its formula that is represented by vertex V. Vertexes without incoming edges are the atomic values such as numbers or strings. Vertexes without outgoing edges are the cells on which on other cell depends. The graph needs to be acyclic because circular references are not defined in a spreadsheet, e.g. the following definitions are incorrect:

    Java Code:
    A1= A2+1
    A2= A1+1
    This limitation makes the creation of recurrent expressions impossible. Evaluations starts at the vertexes without incoming edges and stops at the vertexes without outgoing edges. All the rest is 'view' business and not very interesting. Asking for all the code is just too much to ask for.

    kind regards,

    Jos
