ResultSetIterator

public class ResultSetIterator implements Iterator(Code)

Wraps a ResultSet in an Iterator. This is useful when you want to present a non-database application layer with domain neutral data.

This implementation requires the ResultSet.isLast() method to be implemented.

Constructor Summary
public	ResultSetIterator(ResultSet rs) Constructor for ResultSetIterator.
public	ResultSetIterator(ResultSet rs, RowProcessor convert) Constructor for ResultSetIterator. Parameters: rs - Wrap this `ResultSet` in an `Iterator`. Parameters: convert - The processor to use when converting a row into an `Object[]`.

Method Summary
public boolean	hasNext() Returns true if there are more rows in the ResultSet.
public Object	next() Returns the next row as an `Object[]`. An `Object[]` with the same number of elements ascolumns in the `ResultSet`.
public void	remove() Deletes the current row from the `ResultSet`.
protected void	rethrow(SQLException e) Rethrow the SQLException as a RuntimeException.

Constructor Detail

ResultSetIterator
public ResultSetIterator(ResultSet rs)(Code)
	Constructor for ResultSetIterator. Parameters: rs - Wrap this `ResultSet` in an `Iterator`.

ResultSetIterator
public ResultSetIterator(ResultSet rs, RowProcessor convert)(Code)
	Constructor for ResultSetIterator. Parameters: rs - Wrap this `ResultSet` in an `Iterator`. Parameters: convert - The processor to use when converting a row into an `Object[]`. Defaults to a `BasicRowProcessor`.

Method Detail

hasNext
public boolean hasNext()(Code)
	Returns true if there are more rows in the ResultSet. boolean `true` if there are more rows throws: RuntimeException - if an SQLException occurs.

next
public Object next()(Code)
	Returns the next row as an `Object[]`. An `Object[]` with the same number of elements ascolumns in the `ResultSet`. See Also: java.util.Iterator.next throws: RuntimeException - if an SQLException occurs.

remove
public void remove()(Code)
	Deletes the current row from the `ResultSet`. See Also: java.util.Iterator.remove throws: RuntimeException - if an SQLException occurs.

rethrow
protected void rethrow(SQLException e)(Code)
	Rethrow the SQLException as a RuntimeException. This implementation creates a new RuntimeException with the SQLException's error message. Parameters: e - SQLException to rethrow since: DbUtils 1.1
