Synopsis

The class TableColumn gives read and write access to a column in a table. In particular access to the column description (for name, data type, etc.) and to the column keyword set can be obtained. Another important function is isDefined, which tests if a cell (i.e. table row) in a column contains a value.

The classes ScalarColumn<T> and ArrayColumn<T> have to be used to get/put the data in the column cells. However, TableColumn has get functions for the basic data types (Bool, uChar, Short, uSort, Int, uInt, float, double, Complex, DComplex and String). Opposite to the get functions in ScalarColumn<T>, the TableColumn get functions support data type promotion.

A default constructor is defined to allow construction of an array of TableColumn objects. However, this constructs an object not referencing a column. Functions like get, etc. will fail (i.e. result in a segmentation fault) when used on such objects. The functions isNull and throwIfNull can be used to test on this. The functions attach and reference can fill in the object.

Example

See module Tables .

Constructor & Destructor Documentation

casa::TableColumn::TableColumn ( )

The default constructor creates a null object, i.e.

it does not reference a table column. The sole purpose of this constructor is to allow construction of an array of TableColumn objects. The functions reference and attach can be used to make a null object reference a column. Note that get functions, etc. will cause a segmentation fault when operating on a null object. It was felt it was too expensive to test on null over and over again. The user should use the isNull or throwIfNull function in case of doubt.

casa::TableColumn::TableColumn	(	const Table &	,
		const String &	columnName
	)

Construct the object for a column in the table using its name.

casa::TableColumn::TableColumn	(	const Table &	,
		uInt	columnIndex
	)

Construct the object for a column in the table using its index.

   This allows to loop through all columns in a table as:

           for (uInt=0; i<tab.ncolumn(); i++) {
               TableColumn tabcol(tab,i);
           }

casa::TableColumn::TableColumn ( const TableColumn & )

Copy constructor (reference semantics).

Assignment has reference semantics.

It copies the object, not the data of that column to this column. Function putColumn can be used to copy the data of a column.
It does the same as the reference function.

Copy the value of a cell of that column to a cell of this column.

This function only works for the standard data types. Data type promotion will be done if needed. An exception is thrown if this column is not writable or if the data cannot be converted.

Use the same row numbers for both cells.
