 <DD>This method is invoked when OpenJPA needs to load an object whose
  identity is known but which has not yet been loaded from the data
  store. <code>sm</code> is a partially-set-up state manager for this
  object. The ID and least-derived type information for the instance
  to load can be obtained by invoking
  <code>sm.getObjectId()</code> and <code>sm.getMetaData()</code>.

   When implementing this method, load the data for this object from
  the data store, determine the most-derived subclass of the newly-loaded
  data, and then use the <A HREF="../../../../org/apache/openjpa/kernel/OpenJPAStateManager.html#initialize(java.lang.Class, org.apache.openjpa.kernel.PCState)"><CODE>OpenJPAStateManager.initialize(java.lang.Class, org.apache.openjpa.kernel.PCState)</CODE></A> method to

 <DD>Responsible for writing modifications happened back to the data
  store. If you do not remove the
  <A HREF="../../../../org/apache/openjpa/conf/OpenJPAConfiguration.html#OPTION_INC_FLUSH"><CODE>OpenJPAConfiguration.OPTION_INC_FLUSH</CODE></A> option in
  <A HREF="../../../../org/apache/openjpa/abstractstore/AbstractStoreManager.html#getUnsupportedOptions()"><CODE>AbstractStoreManager.getUnsupportedOptions()</CODE></A>, this will be called only once at the
  end    of a transaction. Otherwise, it may be called periodically
  throughout the course of a transaction.
   If this store manager supports optimistic transactions, datastore
  version information should be updated during flush, and the state
  manager's version indicator should be updated through the
  <A HREF="../../../../org/apache/openjpa/kernel/OpenJPAStateManager.html#setNextVersion(java.lang.Object)"><CODE>OpenJPAStateManager.setNextVersion(java.lang.Object)</CODE></A> method.
   This method will only be invoked if there are meaningful changes
  to store. This differs from the behavior of <A HREF="../../../../org/apache/openjpa/kernel/StoreManager.html#flush(java.util.Collection)"><CODE>StoreManager.flush(java.util.Collection<org.apache.openjpa.kernel.OpenJPAStateManager>)</CODE></A>,
  which may be invoked with a collection of objects in states that
  do not require any datastore action (for example, objects in the
  transient-transactional state).

 <DD>Create a <A HREF="../../../../org/apache/openjpa/lib/rop/ResultObjectProvider.html" title="interface in org.apache.openjpa.lib.rop"><CODE>ResultObjectProvider</CODE></A> that can return all instances
  of <code>type</code>, optionally including subclasses as defined
  by <code>subclasses</code>.
   The implementation of the result provider will typically execute
  some sort of data store query to find all the applicable objects, loop
  through the results, extracting object IDs from the data, and invoke
  <A HREF="../../../../org/apache/openjpa/kernel/StoreContext.html#find(java.lang.Object, org.apache.openjpa.kernel.FetchConfiguration, java.util.BitSet, java.lang.Object, int)"><CODE>StoreContext.find(Object,FetchConfiguration,BitSet,Object,int)</CODE></A>
  on each OID. When invoking this method, the first argument is the OID.
  The second is the given fetch configuration. The
  third argument is a mask of fields to exclude from loading; it will
  typically be null. The fourth argument is an object that will be passed
  through to <A HREF="../../../../org/apache/openjpa/abstractstore/AbstractStoreManager.html#initialize(org.apache.openjpa.kernel.OpenJPAStateManager, org.apache.openjpa.kernel.PCState, org.apache.openjpa.kernel.FetchConfiguration, java.lang.Object)"><CODE>AbstractStoreManager.initialize(org.apache.openjpa.kernel.OpenJPAStateManager, org.apache.openjpa.kernel.PCState, org.apache.openjpa.kernel.FetchConfiguration, java.lang.Object)</CODE></A> or <A HREF="../../../../org/apache/openjpa/abstractstore/AbstractStoreManager.html#load(org.apache.openjpa.kernel.OpenJPAStateManager, java.util.BitSet, org.apache.openjpa.kernel.FetchConfiguration, int, java.lang.Object)"><CODE>AbstractStoreManager.load(org.apache.openjpa.kernel.OpenJPAStateManager, java.util.BitSet, org.apache.openjpa.kernel.FetchConfiguration, int, java.lang.Object)</CODE></A>, and typically will
  contain the actual data to load. For example, for a JDBC-based store
  manager, this might be the result set that is being iterated over. If
  this argument is <code>null</code>, then the <A HREF="../../../../org/apache/openjpa/abstractstore/AbstractStoreManager.html#initialize(org.apache.openjpa.kernel.OpenJPAStateManager, org.apache.openjpa.kernel.PCState, org.apache.openjpa.kernel.FetchConfiguration, java.lang.Object)"><CODE>AbstractStoreManager.initialize(org.apache.openjpa.kernel.OpenJPAStateManager, org.apache.openjpa.kernel.PCState, org.apache.openjpa.kernel.FetchConfiguration, java.lang.Object)</CODE></A> or
  <A HREF="../../../../org/apache/openjpa/abstractstore/AbstractStoreManager.html#load(org.apache.openjpa.kernel.OpenJPAStateManager, java.util.BitSet, org.apache.openjpa.kernel.FetchConfiguration, int, java.lang.Object)"><CODE>AbstractStoreManager.load(org.apache.openjpa.kernel.OpenJPAStateManager, java.util.BitSet, org.apache.openjpa.kernel.FetchConfiguration, int, java.lang.Object)</CODE></A> method will have to issue another command to the data
  store in order to fetch the data to be loaded.
