Class TCellRef

class TCellRef;

Description

Identifies a cell by row and column number.

Members

Defined in TCellRef:

• ExternalizeL(RWriteStream &)constExternalises an object of this class to a write stream.
• InternalizeL(RReadStream &)Internalises an object of this class from a read stream.
• Offset(TInt,TInt)Adds the specified row and column numbers to this cell's row and column values.
• TCellRef()Default constructor.
• TCellRef(TInt,TInt)Constructor taking a row and column number.
• iColThe column number.
• iRowThe row number.
• operator!=(const TCellRef &)constCompares this cell with the specified cell for inequality.
• operator+=(const TCellRef &)Adds the specified cell to this cell.
• operator-=(const TCellRef &)Subtracts the specified cell from this cell.
• operator==(const TCellRef &)constCompares this cell with the specified cell for equality.

inline TCellRef();

Description

Default constructor.

The object's row and column number are undefined.

inline TCellRef(TInt aRow, TInt aCol);

Description

Constructor taking a row and column number.

Parameters

inline TBool operator==(const TCellRef &aCell) const;

Description

Compares this cell with the specified cell for equality.

Parameters

Return value

inline TBool operator!=(const TCellRef &aCell) const;

Description

Compares this cell with the specified cell for inequality.

Parameters

Return value

inline TCellRef& operator+=(const TCellRef &aCell);

Description

Adds the specified cell to this cell.

Addition is the process of adding the specified cell's row and column numbers to this cell's row and column numbers respectively.

Parameters

Return value

inline TCellRef& operator-=(const TCellRef &aCell);

Description

Subtracts the specified cell from this cell.

Subtraction is the process of subtracting the specified cell's row and column numbers from this cell's row and column numbers respectively.

Parameters

Return value

IMPORT_C void Offset(TInt aRowOffset, TInt aColOffset);

Description

Adds the specified row and column numbers to this cell's row and column values.

Parameters

IMPORT_C void InternalizeL(RReadStream &aStream);

Description

Internalises an object of this class from a read stream.

The presence of this function means that the standard templated operator>>(RReadStream &,T &) 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

inline void ExternalizeL(RWriteStream &aStream) const;

Description

Externalises an object of this class to a write stream.

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

Parameters

TInt iRow;

Description

The row number.

TInt iCol;

Description

The column number.
