Advances the iterator to the next element in the underlying collection and returns it.- Returns:
- the next double in the collection
- Throws:
NoSuchElementException
- if the iterator is already exhausted
-
nextIndex
protected final int nextIndex()
Returns the index of the next value in the data structure or a negative value if the iterator is exhausted.- Returns:
- an
int
value - Throws:
java.util.ConcurrentModificationException
- if the underlying collection's size has been modified since the iterator was created.
-
hasNext
public boolean hasNext()
Returns true if the iterator can be advanced past its current location.- Returns:
- a
boolean
value
-
remove
public void remove()
Removes the last entry returned by the iterator. Invoking this method more than once for a single entry will leave the underlying data structure in a confused state.
-
moveToNextIndex
protected final void moveToNextIndex()
Sets the internal index so that the `next' object can be returned.
