                 throws IllegalClassFormatException

Specified by:

transform in interface javax.persistence.spi.ClassTransformer

Throws:

IllegalClassFormatException

getImplementationType

protected String getImplementationType(String className)

This method will do its best to return an implementation type for a given classname. This will allow weaving template classes to have initialized values. We provide default implementations for List, Map, and Set, and will attempt to utilize a default constructor for other classes. If the className contains an '[', we will return null.
