Class Classpath

java.lang.Object

sirius.kernel.Classpath

public class Classpath
extends Object

Retrieves a filtered list of resources in the classpath.

This is used by the Injector to discover and register all classes in the component model. Additionally Babelfish uses this to load all relevant .properties files.

The method used, is to provide a name of a resource which is placed in every component root (jar file etc.) which then can be discovered using Class.getResources.

Once a file pattern is given, all files in the classpath are scanned, starting from the detected roots.
