Constructor & Destructor Documentation

TRangeRef()

TRangeRef

(

)

[inline]

Default constructor.

The object's start cell and end cell are undefined.

TRangeRef(const TCellRef &, const TCellRef &)

TRangeRef	(	const TCellRef &	aFrom,
		const TCellRef &	aTo
	)	[inline]

Constructor taking a start and end cell.

Parameters

const TCellRef & aFrom	The start cell.
const TCellRef & aTo	The end cell.

TRangeRef(TInt, TInt, TInt, TInt)

TRangeRef	(	TInt	aFromRow,
		TInt	aFromCol,
		TInt	aToRow,
		TInt	aToCol
	)	[inline]

Constructor taking a start row and start column number, and an end row and end column number.

Parameters

TInt aFromRow	The start row number.
TInt aFromCol	The start column number.
TInt aToRow	The end row number.
TInt aToCol	The end column number.

Member Functions Documentation

Contains(const TCellRef &)

IMPORT_C TBool

Contains

(

const TCellRef &

aCell

)

const

Tests whether the specified cell is contained within the range.

A range includes its outer perimeter.

Parameters

const TCellRef & aCell

The cell to be tested.

ExternalizeL(RWriteStream &)

IMPORT_C void

ExternalizeL

(

RWriteStream &

aStream

)

const

Externalises an object of this class to a write stream.

The presence of this function means that the standard templated operator<<() can be used to externalise objects of this class.

Parameters

RWriteStream & aStream

Stream to which the object should be externalised.

InternalizeL(RReadStream &)

IMPORT_C void

InternalizeL

(

RReadStream &

aStream

)

Internalises an object of this class from a read stream.

The presence of this function means that the standard templated operator>>() can be used to internalise objects of this class.

Note that the function has assignment semantics. It replaces the old value of the object with a new value read from the read stream.

Parameters

RReadStream & aStream

Stream from which the object is to be internalised.

NoCells()

IMPORT_C TInt

NoCells

(

)

const

Gets the number of cells represented by the range.

NoCols()

TInt

NoCols

(

)

const [inline]

Gets the number of columns represented by the range.

NoRows()

TInt

NoRows

(

)

const [inline]

Gets the number of rows represented by the range.

SetRange(const TCellRef &, const TCellRef &)

void	SetRange	(	const TCellRef &	aFrom,
			const TCellRef &	aTo
		)	[inline]

Sets the cell range to the specified cells.

Parameters

const TCellRef & aFrom	The start cell for the range.
const TCellRef & aTo	The end cell for the range.

SetRange(TInt, TInt, TInt, TInt)

void	SetRange	(	TInt	aFromRow,
			TInt	aFromCol,
			TInt	aToRow,
			TInt	aToCol
		)	[inline]

Sets the cell range to the specified start row and column, and end row and column.

Parameters

TInt aFromRow	The start row number.
TInt aFromCol	The start column number.
TInt aToRow	The end row number.
TInt aToCol	The end column number.

operator!=(const TRangeRef &)

TBool

operator!=

(

const TRangeRef &

aRange

)

const [inline]

Compares this cell range with the specified cell range for inequality.

Parameters

const TRangeRef & aRange

The cell to be compared.

operator==(const TRangeRef &)

IMPORT_C TBool

operator==

(

const TRangeRef &

aRange

)

const

Compares this cell range with the specified cell range for equality.

Parameters

const TRangeRef & aRange

The cell range to be compared.
