getClassLoader

ClassLoader getClassLoader()

ClassLoader is an abstract class. Not an interface. There are parts of the code that requires a ClassLoader and others that requires an ArtifactClassLoader. Ideally I would make ArtifactClassLoader implement ClassLoader interface but there's no such interface. So if I have a method that requires a ClassLoader instance and an ArtifactClassLoader I would have to down cast and assume that it can be down casted or send two parameters, one for the ClassLoader and one for the ArtifactClassLoader: public void doSomething(ArtifactClassLoader acl) { doSomething2(acl); //this requires an ArtifactClassLoader doSomething3((ClassLoader)acl); //this requires a ClassLoader } public void doSomething(ArtifactClassLoader acl, ClassLoader cl) { doSomething2(acl); //this requires an ArtifactClassLoader doSomething3(cl); //this requires a ClassLoader } To overcome that problem seems much better to have a method in ArtifactClassLoader that can actually return a ClassLoader instance: public void doSomething(ArtifactClassLoader acl) { doSomething2(acl); //this requires an ArtifactClassLoader doSomething3(acl.getDomainClassLoader()); //this requires a ClassLoader }

Returns:

class loader to use for this artifact.

dispose

void dispose()
