Package mondrian.server

Class FileRepository

java.lang.Object

mondrian.server.FileRepository

All Implemented Interfaces:

Repository

public class FileRepository
extends Object
implements Repository

Implementation of Repository that reads from a datasources.xml file.

Note that for legacy reasons, the datasources.xml file's root element is called DataSource whereas the olap4j standard calls them Databases. This is why those two concepts are linked, as in getDatabaseNames(RolapConnection) for example.
