Method Detail

next

public final boolean next(RowProcessingState rowProcessingState)

Description copied from interface: JdbcValues

Advances the "cursor position" and returns a boolean indicating whether there is a row available to read via JdbcValues.getCurrentRowValue(int).

Specified by:

next in interface JdbcValues

Returns:

true if there are results

processNext

protected abstract boolean processNext(RowProcessingState rowProcessingState)

previous

public boolean previous(RowProcessingState rowProcessingState)

Description copied from interface: JdbcValues

Specified by:

previous in interface JdbcValues

Returns:

true if there are results available

processPrevious

protected abstract boolean processPrevious(RowProcessingState rowProcessingState)

scroll

public boolean scroll(int numberOfRows,
                      RowProcessingState rowProcessingState)

Description copied from interface: JdbcValues

Specified by:

scroll in interface JdbcValues

Parameters:

numberOfRows - The number of rows to advance. This can also be negative meaning to move in reverse

Returns:

true if there are results available
