UnknownResource

java.lang.Object
- net.sf.saxon.resource.UnknownResource

All Implemented Interfaces:

Resource
```
public class UnknownResource
extends java.lang.Object
implements Resource
```
The class is an implementation of the generic Resource object (typically an item in a collection) representing a resource whose type is not yet known - typically because it uses an unregistered file extension. We attempt to establish a type for the resource when it is opened, by "sniffing" the content.
