Method Detail

getId

String getId()

Returns:

a unique ID for the classloader but meaningful enough for the user to understand which classloader is referring to.

getDelegateNodes

List<ClassLoaderNode> getDelegateNodes()

Returns:

a list of ClassLoaderNode this classloader node will delegate to for finding resources or classes.

getParent

Optional<ClassLoaderNode> getParent()

Returns:

a reference to the parent classloader node in the hierarchy.

getArtifactClassLoader

ArtifactClassLoader getArtifactClassLoader()

Returns:

the ArtifactClassLoader this node refers to.

isMulePlugin

boolean isMulePlugin()

Returns:

indicates if the classloader node is pointing to a mule plugin classloader.

findClassLoaderNode

ClassLoaderNode findClassLoaderNode(ArtifactClassLoader artifactClassLoader)

Find the ClassLoaderNode within this node hierarchy only within the reachable class loaders.

This method assumes that the requested classloader exists in the hierarchy.

Parameters:

artifactClassLoader - the classloader owned by the ClassLoaderNode to search.

Returns:

the found ClassLoaderNode

findPossibleResourceOwners

List<ClassLoaderNode> findPossibleResourceOwners(String resourceName)

Find the list of ClassLoaderNode that owns a private resource with name resourceName.

Parameters:

resourceName - the name of the resource to find

Returns:

the list of ClassLoaderNode owning the resource.

findPossibleClassOwners

List<ClassLoaderNode> findPossibleClassOwners(String className)

Find the list of ClassLoaderNode that owns a private class with name className.

Parameters:

className - the name of the class lo find

Returns:

the list of ClassLoaderNode owning the class.
