Detailed Description

Abstract class. Used for deriving classes with different column types.

This class defines only the column header and no data storage, as the data type is not defined yet. However, we know that the data are stored in a std::vector<> so some virtual methods can already be defined.

Member Function Documentation

virtual double gloria::GloriaTableColumn::DoubleVal ( int  i, int  j = 0  )

pure virtual

Return value of element stored in given cell as double.

Can be used for all column types except StringColumn (if this case 0. is returned). Second argument is used only if cell is a vector. Integers are converted to floats.

Implemented in gloria::GloriaTableColumnOf< T >.

virtual long gloria::GloriaTableColumn::LongVal ( int  i, int  j = 0  )

pure virtual

Return value of element stored in given cell as long.

Can be used only for LongColumn or LongVectorColumn. For other column types 0 is returned. Second argument is used only if cell is a vector.

Implemented in gloria::GloriaTableColumnOf< T >.

virtual string gloria::GloriaTableColumn::StringVal ( int  i )

pure virtual

Return element stored in given cell as string.

If cell contains a vector all elements are included, separated by space (' '). If unit is defined it is appended at the end of the sting.

Implemented in gloria::GloriaTableColumnOf< T >.

virtual string gloria::GloriaTableColumn::StringVal ( int  i, int  j  )

pure virtual

Return element stored in given cell as string.

If cell contains a vector only one vector element (indicated by second argument) is returned. If unit is defined it is appended at the end of the sting.

Implemented in gloria::GloriaTableColumnOf< T >.

virtual int gloria::GloriaTableColumn::ValSize ( int  i )

pure virtual

Returns size of given cell.

Returns:

• 0 - if row i is not found
• 1 - if cell is a single number or string
• size() - if cell is a vector

Implemented in gloria::GloriaTableColumnOf< T >.
