ClasspathResourceLoader (Lucene 9.11.1 core API)

java.lang.Object
- org.apache.lucene.util.ClasspathResourceLoader

All Implemented Interfaces:

ResourceLoader
```
public final class ClasspathResourceLoader
extends Object
implements ResourceLoader
```
Simple ResourceLoader that uses ClassLoader.getResourceAsStream(String) and Class.forName(String,boolean,ClassLoader) to open resources and classes, respectively.
To use this class with the Java Module System, you must open all modules on classpath that contain resources to the org.apache.lucene.core module, otherwise resources can't be looked up. It is recommended to use ModuleResourceLoader for such use cases as this would limit to certain modules.
