Examples of EnhancerMetaData

org.apache.jdo.impl.enhancer.meta.EnhancerMetaData
Provides the JDO meta information neccessary for byte-code enhancement.
Please note: This interface deals with fully qualified names in the JVM notation, that is, with '/' as package separator character (instead of '.').
