excludePackage
public void excludePackage(String packageName)
Add a package name to exclude from decoration (e.g. 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
excludeClass
public void excludeClass(String className)
Add a class name to exclude from decoration (e.g. overriding).Any class name registered here will be handled by the parent ClassLoader in the usual fashion.
- Parameters:
className- the class name to exclude
isExcluded
protected boolean isExcluded(String className)
