Constructor Detail

AreaEvalBase

protected AreaEvalBase(int firstRow,
                       int firstColumn,
                       int lastRow,
                       int lastColumn)

AreaEvalBase

protected AreaEvalBase(AreaI ptg)

Method Detail

getFirstColumn

public final int getFirstColumn()

Description copied from interface: AreaEval

returns the 0-based index of the first col in this area.

Specified by:

getFirstColumn in interface AreaEval

getFirstRow

public final int getFirstRow()

Description copied from interface: AreaEval

returns the 0-based index of the first row in this area.

Specified by:

getFirstRow in interface AreaEval

getLastColumn

public final int getLastColumn()

Description copied from interface: AreaEval

returns the 0-based index of the last col in this area.

Specified by:

getLastColumn in interface AreaEval

getLastRow

public final int getLastRow()

Description copied from interface: AreaEval

returns the 0-based index of the last row in this area.

Specified by:

getLastRow in interface AreaEval

getAbsoluteValue

public final ValueEval getAbsoluteValue(int row,
                                        int col)

Specified by:

getAbsoluteValue in interface AreaEval

Returns:

the ValueEval from within this area at the specified row and col index. Never null (possibly BlankEval). The specified indexes should be absolute indexes in the sheet and not relative indexes within the area.

contains

public final boolean contains(int row,
                              int col)

Description copied from interface: AreaEval

returns true if the cell at row and col specified as absolute indexes in the sheet is contained in this area.

Specified by:

contains in interface AreaEval

containsRow

public final boolean containsRow(int row)

Description copied from interface: AreaEval

returns true if the specified row is in range

Specified by:

containsRow in interface AreaEval

containsColumn

public final boolean containsColumn(int col)

Description copied from interface: AreaEval

returns true if the specified col is in range

Specified by:

containsColumn in interface AreaEval

isColumn

public final boolean isColumn()

Specified by:

isColumn in interface TwoDEval

Returns:

true if the area has just a single column, this also includes the trivial case when the area has just a single cell.

isRow

public final boolean isRow()

Specified by:

isRow in interface TwoDEval

Returns:

true if the area has just a single row, this also includes the trivial case when the area has just a single cell.

getHeight

public int getHeight()

Specified by:

getHeight in interface AreaEval

Specified by:

getHeight in interface TwoDEval

getValue

public final ValueEval getValue(int row,
                                int col)

Specified by:

getValue in interface TwoDEval

Parameters:

row - relative row index (zero based)

col - relative column index (zero based)

Returns:

element at the specified row and column position

getRelativeValue

public abstract ValueEval getRelativeValue(int relativeRowIndex,
                                           int relativeColumnIndex)

Specified by:

getRelativeValue in interface AreaEval

Returns:

the ValueEval from within this area at the specified relativeRowIndex and relativeColumnIndex. Never null (possibly BlankEval). The specified indexes should relative to the top left corner of this area.

getWidth

public int getWidth()

Specified by:

getWidth in interface AreaEval

Specified by:

getWidth in interface TwoDEval

isSubTotal

public boolean isSubTotal(int rowIndex,
                          int columnIndex)

Specified by:

isSubTotal in interface TwoDEval

Returns:

whether cell at rowIndex and columnIndex is a subtotal. By default return false which means 'don't care about subtotals'
