Examples of org.geoserver.platform.GeoServerResourceLoader

org.geoserver.platform.GeoServerResourceLoader
Manages resources in GeoServer.
The loader maintains a search path in which it will use to look up resources. The {@link #baseDirectory} is a member of this path.

Files and directories created by the resource loader are made relative to {@link #baseDirectory}.
```
  File dataDirectory = ... GeoServerResourceLoader loader = new GeoServerResourceLoader( dataDirectory ); loader.addSearchLocation( new File( "/WEB-INF/" ) ); loader.addSearchLocation( new File( "/data" ) ); ... File catalog = loader.find( "catalog.xml" );  
```
