public interface CloseableIterator<T>
Extension to Iterator to provide a close() method. This should be in the JDK.
NOTE: You must call close() method when you are done otherwise the underlying SQL
statement and connection may be kept open.
| Method Summary | |
|---|---|
void |
close()
Close any underlying SQL statements. |
void |
closeQuietly()
Close any underlying SQL statements but swallow any SQLExceptions. |
T |
current()
Return the current result object that we have accessed or null if none. |
T |
first()
Move to the first result and return it or null if none. |
DatabaseResults |
getRawResults()
Return the underlying database results object if any. |
T |
moveRelative(int offset)
Move a relative position in the list and return that result or null if none. |
void |
moveToNext()
Move to the next item in the iterator without calling Iterator.next(). |
T |
nextThrow()

T nextThrow()
throws SQLException
Iterator.next() object in the table or null if none.
SQLException - Throws a SQLException on error since Iterator.next() cannot throw because it is part of the
Iterator definition. It will not throw if there is no next.
T moveRelative(int offset)
throws SQLException
Iterator.next().
moveRelative(-1) is the same as previous() result. This may not work with the default iterator depending
on your database.
offset - Number of rows to move. Positive moves forward in the results. Negative moves backwards.
SQLException
