byte[] transform(
  ClassLoader loader,
  String className,
  Class<?> classBeingRedefined,
  ProtectionDomain protectionDomain,
  byte[] classfileBuffer
)

Invoked when a class is being loaded or redefined. The implementation of this method may transform the supplied class file and return a new replacement class file.

Parameters:: loader - the defining loader of the class to be transformed, may be null if the bootstrap loader; className - the name of the class in the internal form of fully qualified class and interface names; classBeingRedefined - if this is a redefine, the class being redefined, otherwise null; protectionDomain - the protection domain of the class being defined or redefined; classfileBuffer - the input byte buffer in class file format - must not be modified

Return:: a well-formed class file buffer (the result of the transform), or null if no transform is performed

Throws:: TransformerException - if the input does not represent a well-formed class file

Since:: JPA 1.0
