Constructor Detail

HSSFRow

protected HSSFRow()

HSSFRow

protected HSSFRow(Workbook book,
       Sheet sheet,
       int rowNum)

Creates new HSSFRow from scratch. Only HSSFSheet should do this.

Parameters:

book - low-level Workbook object containing the sheet that contains this row

sheet - low-level Sheet object that contains this Row

rowNum - the row number of this row (0 based)

See Also:

HSSFSheet.createRow(int)

HSSFRow

protected HSSFRow(Workbook book,
       Sheet sheet,
       RowRecord record)

Creates an HSSFRow from a low level RowRecord object. Only HSSFSheet should do this. HSSFSheet uses this when an existing file is read in.

Parameters:

book - low-level Workbook object containing the sheet that contains this row

sheet - low-level Sheet object that contains this Row

record - the low level api object this row should represent

See Also:

HSSFSheet.createRow(int)

Method Detail

createCell

public HSSFCell createCell(short column)

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

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

Parameters:

column - - the column number this cell represents

Returns:

HSSFCell a high level representation of the created cell.

createCell

public HSSFCell createCell(short column,
                  int type)

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

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

Parameters:

column - - the column number this cell represents

Returns:

HSSFCell a high level representation of the created cell.

removeCell

public void removeCell(HSSFCell cell)

remove the HSSFCell from this row.

Parameters:

cell - to remove

createCellFromRecord

protected HSSFCell createCellFromRecord(CellValueRecordInterface cell)

create a high level HSSFCell object from an existing low level record. Should only be called from HSSFSheet or HSSFRow itself.

Parameters:

cell - low level cell to create the high level representation from

Returns:

HSSFCell representing the low level record passed in

setRowNum

public void setRowNum(int rowNum)

set the row number of this row.

Parameters:

rowNum - the row number (0-based)

Throws:

java.lang.IndexOutOfBoundsException - if the row number is not within the range 0-65535.

getRowNum

public int getRowNum()

get row number this row represents

Returns:

the row number (0 based)

getCell

public HSSFCell getCell(short cellnum)

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

Parameters:

cellnum - 0 based column number

Returns:

HSSFCell representing that column or null if undefined.

getFirstCellNum

public short getFirstCellNum()

get the number of the first cell contained in this 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 number of the last cell contained in this row PLUS ONE.

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.

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.

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

Parameters:

zHeight - height is zero or not.

getZeroHeight

public boolean getZeroHeight()

get whether or not to display this row with 0 height

Returns:

- zHeight height is zero or not.

setHeightInPoints

public void setHeightInPoints(float height)

set the row's height in points.

Parameters:

height - row height in points

getHeight

public short getHeight()

get the row's height or ff (-1) for undefined/default-height in twips (1/20th of a point)

Returns:

rowheight or 0xff for undefined (use sheet default)

getHeightInPoints

public float getHeightInPoints()

get the row's height or ff (-1) for undefined/default-height in points (20*getHeight())

Returns:

rowheight or 0xff for undefined (use sheet default)

getRowRecord

protected RowRecord getRowRecord()

get the lowlevel RowRecord represented by this object - should only be called by other parts of the high level API

Returns:

RowRecord this row represents

cellIterator

public java.util.Iterator cellIterator()

Returns:

cell iterator of the physically defined cells. Note element 4 may actually be row cell depending on how many are defined!

compareTo

public int compareTo(java.lang.Object obj)

Specified by:

compareTo in interface java.lang.Comparable

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object
