addTransformer back to summary

addTransformer	back to summary
public void addTransformer(ClassTransformer transformer) Add a transformer supplied by the provider that will be called for every new class definition or class redefinition that gets loaded by the loader returned by the `PersistenceUnitInfo#getClassLoader` method. The transformer has no effect on the result returned by the `PersistenceUnitInfo#getNewTempClassLoader` method. Classes are only transformed once within the same classloading scope, regardless of how many persistence units they may be a part of. Parameters transformer:ClassTransformer provider-supplied transformer that the container invokes at class-(re)definition time
