Virtual scalar column using TaQL.

Synopsis

VirtualTaQLColumn is a virtual column engine to define the contents of a column as a TaQL expression in which possibly other columns are used. It is (of course) only possible to get data from the column; puts cannot be done.
The expression result can be a scalar or array of the basic TaQL data types. The column data type has to be conformant with that TaQL type, thus a column of any integer type has to be used for an integer TaQL result.
Caution: One has to be careful with deleting columns; If in an existing table a TaQL expression uses a deleted column, the expression cannot be parsed anymore and the table cannot be opened anymore; In the future the Table System will be made more forgiving;

Example

The following example creates a table with a few columns. One column is virtual and has a random value if Col3 is true. Otherwise it has value 0.

// Create the table description.
TableDesc td;
td.addColumn (ScalarColumnDesc<DComplex>("Col1"));
td.addColumn (ScalarColumnDesc<Int>("Col2"));
td.addColumn (ScalarColumnDesc<Bool>("Col3"));
td.addColumn (ScalarColumnDesc<Double>("ColVirt"));
// Now create a new table from the description.
SetupNewTable newTab("tmtest", td, Table::New);
// Define the expression of the virtual column and bind the column to it.
// The other columns are by default bound to StandardStMan.
VirtualTaQLColumn engine("iif(Col3,rand(),0)");
newTab.bindColumn("ColVirt", engine);
Table tab(newTab);

privatevirtual

Get the array value in the given row.

The argument dataPtr is in fact an Array<T>*, but a void* is needed to be generic. The array pointed to by dataPtr has to have the correct shape (which is guaranteed by the ArrayColumn get function). The default implementation throws an "invalid operation" exception.

Reimplemented from casacore::DataManagerColumn.
