Prerequisite

Etymology

TabVecScaCol is the class dealing with a table vector representing a column of scalars in a table.

Synopsis

TabVecScaCol objects are a view on a column of scalars in a table. The semantics of these table vectors are the same as the normal vectors. So for example, changing an element in the table vector means changing the corresponding field in the underlying table.

Motivation

TabVecScaCol is derived from TabVecRep and as such it is a letter for the envelope class TableVector.

Constructor & Destructor Documentation

template<class T >

casacore::TabVecScaCol< T >::TabVecScaCol

(

const TableColumn &

column

)

Create a table vector from the given table column.

This constructor is for TableVector and allows elements to be changed.

template<class T >

casacore::TabVecScaCol< T >::~TabVecScaCol

(

)

Destruct the object.
