ListRowIterator(java.util.List list) |
| Modifier and Type | Method and Description |
|---|---|
Row |
current()
Returns the last
Rowreturned 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 Rows when traversing the list
in the forward direction. |
boolean |
hasPrevious()
Returns
true if I have more Rows when traversing the list
in the reverse direction. |
Row |
last()
|
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 Rowin the list). |
int |
size()
Retunrs the current size of the underlaying row collection
