All known Subclasses: org.springframework.instrument.classloading.SimpleInstrumentableClassLoader, org.springframework.instrument.classloading.SimpleThrowawayClassLoader,
| OverridingClassLoader | | public class OverridingClassLoader extends ClassLoader (Code) | | ClassLoader that does not always delegate to the
parent loader, as normal class loaders do. This enables, for example,
instrumentation to be forced in the overriding ClassLoader, or a
"throwaway" class loading behavior, where selected classes are
temporarily loaded in the overriding ClassLoader, in order to be load
an instrumented version of the class in the parent ClassLoader later on.

| OverridingClassLoader | | public OverridingClassLoader(ClassLoader parent)(Code) | | Create a new OverridingClassLoader for the given class loader.
Parameters:
parent - the ClassLoader to build an overriding ClassLoader for |
| excludeClass | | public void excludeClass(String className)(Code) | | Add a class name to exclude from overriding.
Any class name registered here will be handled by
the parent ClassLoader in the usual fashion.
Parameters:
className - the class name to exclude |
| excludePackage | | public void excludePackage(String packageName)(Code) | | Add a package name to exclude from overriding.
Any class whose fully-qualified name starts with the name registered
here will be handled by the parent ClassLoader in the usual fashion.
Parameters:
packageName - the package name to exclude |
| isEligibleForOverriding | | protected boolean isEligibleForOverriding(String className)(Code) | | Determine whether the specified class is eligible for overriding
by this class loader.
The default implementation checks against excluded packages and classes.
Parameters:
className - the class name to check whether the specified class is eligible

| transformIfNecessary | | protected byte[] transformIfNecessary(String name, byte[] bytes)(Code) | | Transformation hook to be implemented by subclasses.
The default implementation simply returns the given bytes as-is.
Parameters:
name - the fully-qualified name of the class being transformed
Parameters:
bytes - the raw bytes of the class the transformed bytes (never null;same as the input bytes if the transformation produced no changes) |
