public class DynamicClassWriter extends Object
The intent is to provide a common writer for dynamic JPA entities but also allow for subclasses of this to be used in more complex writing situations such as SDO and DBWS.
Instances of this class and any subclasses are maintained within the
DynamicClassLoader.getClassWriters()
and
DynamicClassLoader.defaultWriter
for the life of the class loader so
it is important that no unnecessary state be maintained that may effect
memory usage.
