Class SheetRangeImpl

java.lang.Object
  |
  +--jxl.biff.SheetRangeImpl

All Implemented Interfaces:

Range

public class SheetRangeImpl

extends java.lang.Object

implements Range

Implementation class for the Range interface. This merely holds the raw range information. This implementation is used for ranges which are present on the current working sheet, so the getSheetIndex merely returns -1

Field Summary

private int	column1 The column number of the cell at the top left of the range
private int	column2 The column index of the cell at the bottom right
private int	row1 The row number of the cell at the top left of the range
private int	row2 The row index of the cell at the bottom right
private Sheet	sheet A handle to the sheet containing this range

Constructor Summary

SheetRangeImpl(Sheet s, int c1, int r1, int c2, int r2)
Constructor

SheetRangeImpl(SheetRangeImpl c, Sheet s)
A copy constructor used for copying ranges between sheets

Method Summary

boolean	equals(java.lang.Object o) Standard equals method
Cell	getBottomRight() Gets the cell at the bottom right of this range
int	getFirstSheetIndex() Not supported.
int	getLastSheetIndex() Not supported.
Cell	getTopLeft() Gets the cell at the top left of this range
void	insertColumn(int c) A column has been inserted, so adjust the range objects accordingly
void	insertRow(int r) A row has been inserted, so adjust the range objects accordingly
boolean	intersects(SheetRangeImpl range) Sees whether there are any intersections between this range and the range passed in.
void	removeColumn(int c) A column has been removed, so adjust the range objects accordingly
void	removeRow(int r) A row has been removed, so adjust the range objects accordingly
java.lang.String	toString() To string method - primarily used during debugging

Field Detail

sheet

private Sheet sheet

A handle to the sheet containing this range

column1

private int column1

The column number of the cell at the top left of the range

row1

private int row1

The row number of the cell at the top left of the range

column2

private int column2

The column index of the cell at the bottom right

row2

private int row2

The row index of the cell at the bottom right

Constructor Detail

SheetRangeImpl

public SheetRangeImpl(Sheet s,
                      int c1,
                      int r1,
                      int c2,
                      int r2)

Constructor

SheetRangeImpl

public SheetRangeImpl(SheetRangeImpl c,
                      Sheet s)

A copy constructor used for copying ranges between sheets

Parameters:

r - the range to copy from

s - the writable sheet

Method Detail

getTopLeft

public Cell getTopLeft()

Gets the cell at the top left of this range

Specified by:

getTopLeft in interface Range

Returns:

the cell at the top left

getBottomRight

public Cell getBottomRight()

Gets the cell at the bottom right of this range

Specified by:

getBottomRight in interface Range

Returns:

the cell at the bottom right

getFirstSheetIndex

public int getFirstSheetIndex()

Not supported. Returns -1, indicating that it refers to the current sheet

Specified by:

getFirstSheetIndex in interface Range

Returns:

-1

getLastSheetIndex

public int getLastSheetIndex()

Not supported. Returns -1, indicating that it refers to the current sheet

Specified by:

getLastSheetIndex in interface Range

Returns:

-1

intersects

public boolean intersects(SheetRangeImpl range)

Sees whether there are any intersections between this range and the range passed in. This method is used internally by the WritableSheet to verify the integrity of merged cells, hyperlinks etc. Ranges are only ever compared for the same sheet

Parameters:

the - range to compare against

Returns:

TRUE if the ranges intersect, FALSE otherwise

toString

public java.lang.String toString()

To string method - primarily used during debugging

Overrides:

toString in class java.lang.Object

Returns:

the string version of this object

insertRow

public void insertRow(int r)

A row has been inserted, so adjust the range objects accordingly

Parameters:

r - the row which has been inserted

insertColumn

public void insertColumn(int c)

A column has been inserted, so adjust the range objects accordingly

Parameters:

c - the column which has been inserted

removeRow

public void removeRow(int r)

A row has been removed, so adjust the range objects accordingly

Parameters:

r - the row which has been inserted

removeColumn

public void removeColumn(int c)

A column has been removed, so adjust the range objects accordingly

Parameters:

c - the column which has been removed

equals

public boolean equals(java.lang.Object o)

Standard equals method

Overrides:

equals in class java.lang.Object

Returns:

TRUE if the two objects are the same, FALSE otherwise
