@SuppressWarnings:unchecked
canHandleback to summary
public static boolean canHandle(final Class<?> classLoaderClass, final LogNode log)

Check whether this ClassLoaderHandler can handle a given ClassLoader.

Parameters
classLoaderClass:Class<?>

the ClassLoader class or one of its superclasses.

log:LogNode

the log

Returns:boolean

true if this ClassLoaderHandler can handle the ClassLoader.

findClassLoaderOrderback to summary
public static void findClassLoaderOrder(final ClassLoader classLoader, final ClassLoaderOrder classLoaderOrder, final LogNode log)

Find the ClassLoader delegation order for a ClassLoader.

Parameters
classLoader:ClassLoader

the ClassLoader to find the order for.

classLoaderOrder:ClassLoaderOrder

a ClassLoaderOrder object to update.

log:LogNode

the log

findClasspathOrderback to summary
public static void findClasspathOrder(final ClassLoader classLoader, final ClasspathOrder classpathOrder, final ScanSpec scanSpec, final LogNode log)

Find the classpath entries for the associated ClassLoader.

Parameters
classLoader:ClassLoader
