getClassLoader
public 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
}
- Specified by:
getClassLoader
in interface ArtifactClassLoader
- Returns:
- class loader to use for this artifact.
