Class AbstractDataProvider

java.lang.Object

org.fastnate.data.AbstractDataProvider

All Implemented Interfaces:

DataProvider

public abstract class AbstractDataProvider
extends Object
implements DataProvider

Implementations of this class will automatically instantiated by the EntityImporter. The constructor must either be the "no arguments constructor" - or accept one or more of the following parameters:

• the data directory as File
• the Properties settings
• references to other DataProviders

If references to other DataProviders are used in the constructor, the DataProvider.buildEntities() method of these providers are called before our DataProvider.buildEntities().
