Examples of WeavingClassLoader

er.profiling.classloader.WeavingClassLoader
The WeavingClassLoader is a custom URLClassLoader that implements the same functionality as the -javaagent transformation feature, passing all classes through the ClassTransformer prior to definition. When this classloader is enabled as a "root loader" and not a conventional hierarchical classloader it is important to use caution as it may not work as expected in some cases. @author q
kilim.WeavingClassLoader
Classloader that loads classes from the classpath spec given by the system property "kilim.class.path" and weaves them dynamically.
org.codehaus.aspectwerkz.hook.impl.WeavingClassLoader
Very basic classloader that do online weaving.
This classloader can be used thru several means
- as a URLClassLoader in a custom development
- as a MainClass to allow on the fly weaving (without support for classloader hierarchy)
It can also be used for debugging step by step in any IDE @author Alexandre Vasseur @todo rewrite based on SUN src (definePackage missing)
