Description copied from interface: ClassLoaderHandler

Determine if a given ClassLoader can be handled (meaning that its classpath elements can be extracted from it), and if it can, extract the classpath elements from the ClassLoader and register them with the ClasspathFinder using classpathFinder.addClasspathElement(pathElement) or classpathFinder.addClasspathElements(path).

Specified by:

handle in interface ClassLoaderHandler

Parameters:

classloader - The ClassLoader class to attempt to handle. If you can't directly use instanceof (because you are using introspection so that your ClassLoaderHandler implementation can be added to the upstream FastClasspathScanner project), you should iterate through the ClassLoader's superclass lineage to ensure subclasses of the target ClassLoader are correctly detected.

classpathFinder - The ClasspathFinder to register any discovered classpath elements with.

log - A logger instance -- write debug information using log.log("message"), then switch on verbose mode to view it.

Returns:

true if the passed ClassLoader was handled by this ClassLoaderHandler, else false.
