Thanks Andun :)
Here are couple more comments:
1) WhiteboardBehavior.respond: how the string editedElement looks like?
Maybe it is better to create *enum* with element names and use
*switch*instead of nested if...else...if
2) WhiteboardBehavior.renderHead: I would recommend JSONArray instead of
concatenating JSONObject.toString(). The code will be very smple in this
case:
for (Element e : elementMap.values()) {
array.add(element.getJSON());
}
3) the bullet above also will require getJSON() method be changed to return
JSONObject
4) I also would change
Boolean hidden=null;
try{
hidden=(Boolean)object.get("hidden");
}catch(JSONException e){
//Add Error Handling
}
this.hidden = hidden;
to be just:
try{
this.hidden=(Boolean)object.get("hidden");
}catch(JSONException e){
//Add Error Handling
}
less code, same effect :)
