DataSource Class

Uses

GeoCalcPBW::GeoBase

Description

The DataSource class provides properties and methods that allow the user to interact with a data source XML file. A description of how to use the DataSource can be found here.

Public Constructors

Constructor	Description
DataSource	Creates a new instance of the DataSource class
CreateDataSource	Creates a new instance of the DataSource class

Public Methods

Method	Description
CommitToFile	Saves the DataSource to a file
