 <div class="block">This class is a helper class for JDO implementations.  It contains methods
  to register metadata for persistence-capable classes and to perform common
  operations needed by implementations, not by end users.
  <P><code>JDOImplHelper</code> allows construction of instances of
  persistence-capable classes without using reflection.
  <P>Persistence-capable classes register themselves via a static method
  at class load time.
  There is no security restriction on this access.  JDO implementations
  get access to the functions provided by this class only if they are
  authorized by the security manager.  To avoid having every call go through
  the security manager, only the call to get an instance is checked.  Once an
  implementation
  has an instance, any of the methods can be invoked without security checks.</div>
