Description

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.

Template Type Argument Requirements (T)

To Do

Member Description

TabVecScaCol (const ROTableColumn& column)

Create a table vector from the given table column. This constructor is for ROTableVector and does not allow elements to be changed.

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 ()

Destruct the object.

uInt nelem() const

Nr of elements (ie. #rows in table).

T value (uInt index) const

Get a value.

void getVal (uInt index, T&) const

Get a value.

void putVal (uInt index, const T&)

Put a value.

void set (const T&)

Set entire vector to a value.
