- - uk.ac.starlink.datanode.factory.SourceDataNodeBuilder

```
public class SourceDataNodeBuilder
extends DataNodeBuilder
```
A DataNodebuilder which tries to build a DataNode from a DataSource object. It examines the file and may invoke a constructor of a DataNode subclass if it knows of one which is likely to be suitable. It will only try constructors which might have a chance.
Part of its duties involve constructing a DOM from a DataSource which looks like XML and offering it to known XML consumers.
