Method Detail

toString

public String toString()

Overrides:

toString in class Object

getArtifactName

public String getArtifactName()

Specified by:

getArtifactName in interface ArtifactClassLoader

Returns:

the artifact unique identifier

getClassLoader

public ClassLoader getClassLoader()

Description copied from interface: ArtifactClassLoader

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.

dispose

public void dispose()

Description copied from interface: ArtifactClassLoader

Gets rid of the class loader resources.

Specified by:

dispose in interface ArtifactClassLoader

findResource

public URL findResource(String name)

Specified by:

findResource in interface ArtifactClassLoader

Overrides:

findResource in class URLClassLoader

Parameters:

name - name of the resource to find.

Returns:

the resource URL, null if it doesn't exists.
