java.lang.Object
- org.bridgedb.DataSource

```
public final class DataSource
extends Object
```
Contains information about a certain DataSource. This includes:
- Its full name ("Ensembl")
- Its system code ("En")
- Its main url ("http://www.ensembl.org")
- Id-specific url's ("http://www.ensembl.org/Homo_sapiens/Gene/Summary?g=" + id)
The DataSource class uses the extensible enum pattern. You cannot instantiate DataSources directly, instead you have to use one of the constants from the org.bridgedb.bio module such as BioDataSource.ENSEMBL, or the getBySystemcode or "getByFullname" methods. These methods return a predefined DataSource object if it exists. If a predefined DataSource for a requested SystemCode doesn't exists, a new one springs to life automatically. This can be used when the user requests new, unknown data sources. If you call getBySystemCode twice with the same argument, it is guaranteed that you get the same return object. However, there is no way to combine a new DataSource with a new FullName unless you use the "register" method.
This way any number of pre-defined DataSources can be used, but plugins can define new ones and you can handle unknown data sources in the same way as predefined ones.
Definitions for common DataSources can be found in
