Modifier and Type | Method and Description |
---|---|
Row |
current()
Returns the last
Row returned by me (by RowIterator.next() ,RowIterator.previous() ,
RowIterator.first() ,RowIterator.last() , etc.). |
int |
currentIndex()
Returns the index of the
RowIterator.current() row, if any. |
boolean |
hasCurrent()
Returns
true if I have a current Row . |
boolean |
hasNext()
Returns
true if I have more Row s when traversing the list
in the forward direction. |
boolean |
hasPrevious()
Returns
true if I have more Row s when traversing the list
in the reverse direction. |
Row |
next()
|
int |
nextIndex()
Returns the index of the
RowIterator.next() row, if any, or the number of elements is
the iterator if we've reached the end. |
Row |
previous()
|
int |
previousIndex()
Returns the index of the
RowIterator.previous() row, if any, or -1 if we're add the
beginning of the list. |
void |
reset()
Re-initialize this
RowIterator to its initial state (positioned just
before the first Row in the list). |
