Can you give an example?

Java class loaders,

http://java.sun.com/j2se/1.4.1/docs/api/java/lang/ClassLoader.html

from them one can retrieve java classes or data resources.

E.g. when Jython is embedded, the embedding enviroment can have setup classloaders to access Jython code and other bundled data ( getResource, getResourceAsStream). And our users would like to bundle and access Python code from there.

They are purely runtime object, and an abstraction over the filesystem, zip files or some remote code repository of whatever...

regards.
