java - JavaFX Application - architectural issue - diffrent lists of inherited classes -

i'm learning javafx tutorial http://code.makery.ch/library/javafx-8-tutorial/, in app i've made login module , want create 3 diffrent views - depending on type of user: admin, patient, doctor, , of them inherit user class. create doctor view , keep list of patients in main class:

private observablelist<patient> patientdata = fxcollections             .observablearraylist();      public observablelist<patient> getpatientdata() {         return patientdata;     }      public main() {         patientdata.add(new patient("hans", "muster", 23));     }  

i dont know should next move be. if make 1 list user , keep them doctors, patients , admins problem generating proper views, cause e.g doctor have patients' list. big problem me how serialize xml. if make 3 separate list won't 'elegant' way think.

you create single observablelist<user>, , populate various views using filteredlist.

e.g.

observablelist<user> userlist = fxcollections.observablearraylist();  // ...  listview<user> patientview = new listview<>(); patientview.setitems(new filteredlist<>(userlist, patient.class::isinstance)); 

if want listview<patient> instead of listview<user>, easiest way use easybind library:

listview<patient> patientview = new list<view>(); patientview.setitems(easybind.map(new filteredlist<>(userlist, patient.class::isinstance),      patient.class::cast);
