Constructor Detail

SXSSFRow

public SXSSFRow(SXSSFSheet sheet,
                int initialSize)

Method Detail

allCellsIterator

public Iterator<Cell> allCellsIterator()

hasCustomHeight

public boolean hasCustomHeight()

iterator

public Iterator<Cell> iterator()

Specified by:

iterator in interface Iterable<Cell>

createCell

public Cell createCell(int column)

Use this to create new cells within the row and return it.

The cell that is returned is a Cell.CELL_TYPE_BLANK. The type can be changed either through calling setCellValue or setCellType.

Specified by:

createCell in interface Row

Parameters:

column - - the column number this cell represents

Returns:

Cell a high level representation of the created cell.

Throws:

IllegalArgumentException - if columnIndex < 0 or greater than the maximum number of supported columns (255 for *.xls, 1048576 for *.xlsx)

createCell

public Cell createCell(int column,
                       int type)

Use this to create new cells within the row and return it.

The cell that is returned is a Cell.CELL_TYPE_BLANK. The type can be changed either through calling setCellValue or setCellType.

Specified by:

createCell in interface Row

Parameters:

column - - the column number this cell represents

Returns:

Cell a high level representation of the created cell.

Throws:

IllegalArgumentException - if columnIndex < 0 or greate than a maximum number of supported columns (255 for *.xls, 1048576 for *.xlsx)

removeCell

public void removeCell(Cell cell)

Remove the Cell from this row.

Specified by:

removeCell in interface Row

Parameters:

cell - the cell to remove

setRowNum

public void setRowNum(int rowNum)

Set the row number of this row.

Specified by:

setRowNum in interface Row

Parameters:

rowNum - the row number (0-based)

Throws:

IllegalArgumentException - if rowNum < 0

getRowNum

public int getRowNum()

Get row number this row represents

Specified by:

getRowNum in interface Row

Returns:

the row number (0 based)

getCell

public Cell getCell(int cellnum)

Get the cell representing a given column (logical cell) 0-based. If you ask for a cell that is not defined....you get a null.

Specified by:

getCell in interface Row

Parameters:

cellnum - 0 based column number

Returns:

Cell representing that column or null if undefined.

See Also:

getCell(int, org.zkoss.poi.ss.usermodel.Row.MissingCellPolicy)

getCell

public Cell getCell(int cellnum,
                    Row.MissingCellPolicy policy)

Returns the cell at the given (0 based) index, with the specified Row.MissingCellPolicy

Specified by:

getCell in interface Row

Returns:

the cell at the given (0 based) index

Throws:

IllegalArgumentException - if cellnum < 0 or the specified MissingCellPolicy is invalid

See Also:

Row.RETURN_NULL_AND_BLANK, Row.RETURN_BLANK_AS_NULL, Row.CREATE_NULL_AS_BLANK

getFirstCellNum

public short getFirstCellNum()

Get the number of the first cell contained in this row.

Specified by:

getFirstCellNum in interface Row

Returns:

short representing the first logical cell in the row, or -1 if the row does not contain any cells.

getLastCellNum

public short getLastCellNum()

Gets the index of the last cell contained in this row PLUS ONE. The result also happens to be the 1-based column number of the last cell. This value can be used as a standard upper bound when iterating over cells:

 short minColIx = row.getFirstCellNum();
 short maxColIx = row.getLastCellNum();
 for(short colIx=minColIx; colIx<maxColIx; colIx++) {
   Cell cell = row.getCell(colIx);
   if(cell == null) {
     continue;
   }
   //... do something with cell
 }
 

Specified by:

getLastCellNum in interface Row

Returns:

short representing the last logical cell in the row PLUS ONE, or -1 if the row does not contain any cells.

getPhysicalNumberOfCells

public int getPhysicalNumberOfCells()

Gets the number of defined cells (NOT number of cells in the actual row!). That is to say if only columns 0,4,5 have values then there would be 3.

Specified by:

getPhysicalNumberOfCells in interface Row

Returns:

int representing the number of defined cells in the row.

setHeight

public void setHeight(short height)

Set the row's height or set to ff (-1) for undefined/default-height. Set the height in "twips" or 1/20th of a point.

Specified by:

setHeight in interface Row

Parameters:

height - rowheight or 0xff for undefined (use sheet default)

setZeroHeight

public void setZeroHeight(boolean zHeight)

Set whether or not to display this row with 0 height

- zHeight height is zero or not.

setHeightInPoints

public void setHeightInPoints(float height)

Set the row's height in points.

Specified by:

setHeightInPoints in interface Row

Parameters:

height - the height in points. -1 resets to the default height

Get the row's height measured in twips (1/20th of a point). If the height is not set, the default worksheet value is returned, See Sheet.getDefaultRowHeightInPoints()

Specified by:

getHeight in interface Row
