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

◆ TabVecScaCol()

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.

◆ ~TabVecScaCol()

template<class T >
casacore::TabVecScaCol< T >::~TabVecScaCol ( )

Destruct the object.

◆ nelem()

template<class T >
rownr_t casacore::TabVecScaCol< T >::nelem ( ) const
virtual

Nr of elements (ie.

#rows in table).

Reimplemented from casacore::TabVecRep< T >.

◆ putVal()

template<class T >
void casacore::TabVecScaCol< T >::putVal ( rownr_t  index,
const T &   
)
virtual

Put a value.

Implements casacore::TabVecRep< T >.

◆ set()

template<class T >
void casacore::TabVecScaCol< T >::set ( const T &  )
virtual

Set entire vector to a value.

Implements casacore::TabVecRep< T >.

◆ value()

template<class T >
T casacore::TabVecScaCol< T >::value ( rownr_t  index) const
