Method Detail

contains

public 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

containsColumn

public boolean containsColumn(int col)

Description copied from interface: AreaEval

returns true if the specified col is in range

Specified by:

containsColumn in interface AreaEval

containsRow

public boolean containsRow(int row)

Description copied from interface: AreaEval

returns true if the specified row is in range

Specified by:

containsRow in interface AreaEval

getAbsoluteValue

public 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.

getFirstColumn

public 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 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

getHeight

public int getHeight()

Specified by:

getHeight in interface AreaEval

Specified by:

getHeight in interface TwoDEval

getLastColumn

public 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 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

getRelativeValue

public ValueEval getRelativeValue(int r,
                                  int c)

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

offset

public AreaEval offset(int relFirstRowIx,
                       int relLastRowIx,

                       int relLastColIx)

Description copied from interface: AreaEval

Creates an AreaEval offset by a relative amount from from the upper left cell of this area

Specified by:

offset in interface AreaEval
