                         ClasspathManager manager)

Description copied from interface: ClassLoadingStatsHook

Gets called by a classpath manager during ClasspathManager.findLocalResource(String) after searching the local classloader for a resource. A classpath manager will call this method for each configured class loading stat hook.

Specified by:

postFindLocalResource in interface ClassLoadingStatsHook

Parameters:

name - the name of the requested resource

resource - the URL to the requested resource or null if not found

recordClassDefine

public void recordClassDefine(String name,
                     Class<?> clazz,
                     byte[] classbytes,
                     ClasspathEntry classpathEntry,
                     BundleEntry entry,
                     ClasspathManager manager)

Description copied from interface: ClassLoadingStatsHook

Gets called by a classpath manager after an attempt is made to define a class. This method allows a class loading stat hook to record data about a class definition.

Specified by:

recordClassDefine in interface ClassLoadingStatsHook

Parameters:

name - the name of the class that got defined

clazz - the class object that got defined or null if an error occurred while defining a class
