 *<B>Assertion Description: </B>
The enhancer modifies field accesses to guarantee that the values of fields
are retrieved from the data store prior to application usage.
<OL TYPE="A">
<LI>For any field access that reads the value of a field, the getfield byte code
is replaced with a call to a generated local method, <code>jdoGetXXX</code></LI>
<LI>For any field access that stores the new value of a field, the putfield
byte code is replaced with a call to a generated local method,
<code>jdoSetXXX</code></LI>
</OL>
