Re: [classad-users] get ListExpr components (java)

[Nicholas Coleman <ncoleman@xxxxxxxxxxx>]

To my knowledge there is currently no method in ListExpr corresponding to
GetComponents.  You can fairly easily simulate this method using the
size() and sub() methods in ListExpr:
  ListExpr listexpr;
  ...
  LinkedList list;
  for(int i = 0; i < listexpr.size(); i++) {
    list.add(listexpr.sub(i));
  }
