ResourceResolver (EUGene :: EUGene Core 3.0-alpha-40 API)

java.lang.Object
- org.nuiton.eugene.ResourceResolver

All Implemented Interfaces:

URIResolver

Direct Known Subclasses:

FasterCachedResourceResolver
```
public class ResourceResolver
extends Object
implements URIResolver
```
ResourceResolver is a URIResolver for XSL transformation.

Its purpose is to catch the XSL document(...) function call and return a valid data source only if the wanted resource is present in the project resources.

The main goal of ResourceResolver is to retrieve datasources locally, if the wanted resource is not present in project resource then null will be returned.
The resolve function search for the file part of href parameter:
- href: http://argouml.org/profiles/uml14/default-uml14.xmi
- file part: default-uml14.xmi.
The resource is searched this way:
- eg: [file part extension]/[file part]
- eg: xmi/default-uml14.xmi
You should assign this ResourceResolver on Transformer but not on TransformerFactory.
