Class CellRangeAddressList

java.lang.Object

org.zkoss.poi.ss.util.CellRangeAddressList

Direct Known Subclasses:

CellRangeAddressList

public class CellRangeAddressList
extends java.lang.Object

Implementation of the cell range address lists,like is described in OpenOffice.org's Excel Documentation: excelfileformat.pdf sec 2.5.14 - 'Cell Range Address List' In BIFF8 there is a common way to store absolute cell range address lists in several records (not formulas). A cell range address list consists of a field with the number of ranges and the list of the range addresses. Each cell range address (called an ADDR structure) contains 4 16-bit-values.

CellRangeAddressList

public CellRangeAddressList(RecordInputStream in)

Parameters:

in - the RecordInputstream to read the record from

Method Detail

countRanges

public int countRanges()

Get the number of following ADDR structures. The number of this structures is automatically set when reading an Excel file and/or increased when you manually add a new ADDR structure . This is the reason there isn't a set method for this field .

Returns:

number of ADDR structures

addCellRangeAddress

public void addCellRangeAddress(int firstRow,
                                int firstCol,

                                int lastCol)

Add a cell range structure.

Parameters:

firstRow - - the upper left hand corner's row
