Parameters:

rows - list of Row instances

columnDefinition - ColumnDefinition for this result set

Method Detail

addRow

public void addRow(Row row)

Description copied from interface: ResultsetRows

Adds a row.

Specified by:

addRow in interface ResultsetRows

Parameters:

row - the row to add

afterLast

public void afterLast()

Description copied from interface: ResultsetRows

Moves to after last.

Specified by:

afterLast in interface ResultsetRows

beforeFirst

public void beforeFirst()

Description copied from interface: ResultsetRows

Moves to before first.

Specified by:

beforeFirst in interface ResultsetRows

beforeLast

public void beforeLast()

Description copied from interface: ResultsetRows

Moves to before last.

Specified by:

beforeLast in interface ResultsetRows

get

public Row get(int atIndex)

Description copied from interface: RowList

Optionally retrieve Row at index n. Only works on non dynamic row lists.

Specified by:

get in interface RowList

Parameters:

atIndex - row number

Returns:

Row

getPosition

public int getPosition()

Description copied from interface: RowList

Returns the current position.

Specified by:

getPosition in interface RowList

Returns:

the current row number

hasNext

public boolean hasNext()
