Public Functions

DatasourceValuePointer(irow, icol, backendObject, datasource)

Typically called only inside a clove::Datasource implementation. From outside, you should use clove::Datasource::valuePointer.

Parameters

• irow: The row index.

• icol: The column index.

• backendObject: The backend object. This depends on the datasource implementation.

• datasource: The owning clove::Datasource.

irow

The row index.

icol

The column index.

datasource

The owning clove::Datasource.

backendObject

The backend object.

This depends on the datasource implementation.
