Hi,
I'm just synching my local source to the latest ptolemy souce
tarball.
I noticed that BasicZList.java has been changed.
I don't like the change made to BasicZList$GSet.figuresFromFront (approx
line 251).
Previously it was:
public Iterator figuresFromFront() {
return new Iterator() {
int cursor = _currentFigures.size();
public boolean hasNext() {
return cursor > 0;
}
public Object next() {
cursor--;
return _currentFigures.get(cursor);
}
public void remove() {
throw new UnsupportedOperationException(
"Cannot delete figure from geometric set");
}
};
}
and it has been changed to:
public Iterator figuresFromFront() {
return new Iterator() {
int cursor = _currentFigures.size();
public boolean hasNext() throws NoSuchElementException {
return cursor > 0;
}
public Object next() {
if (cursor <= 0) {
throw new NoSuchElementException("Can't get " +
cursor
+ "'th element from BasicZList of size "
+ _currentFigures.size());
}
cursor--;
return _currentFigures.get(cursor);
}
public void remove() {
throw new UnsupportedOperationException(
"Cannot delete figure from geometric set");
}
};
}
It looks as though the throws designator has been added to the wrong
member. I think it should have been added to next() and not hasNext().
