32+ * Indicates an error with the <code>SyncProvider</code> mechanism. This exception
33+ * is created by a <code>SyncProvider</code> abstract class extension if it
34+ * encounters violations in reading from or writing to the originating data source.
35+ * <P>
36+ * If it is implemented to do so, the <code>SyncProvider</code> object may also create a
37+ * <code>SyncResolver</code> object and either initialize the <code>SyncProviderException</code>
38+ * object with it at construction time or set it with the <code>SyncProvider</code> object at
39+ * a later time.
40+ * <P>
41+ * The method <code>acceptChanges</code> will throw this exception after the writer
42+ * has finished checking for conflicts and has found one or more conflicts. An
43+ * application may catch a <code>SyncProviderException</code> object and call its
44+ * <code>getSyncResolver</code> method to get its <code>SyncResolver</code> object.
45+ * See the code fragment in the interface comment for
46+ * <a href="SyncResolver.html"><code>SyncResolver</code></a> for an example.
47+ * This <code>SyncResolver</code> object will mirror the <code>RowSet</code>
48+ * object that generated the exception, except that it will contain only the values
49+ * from the data source that are in conflict. All other values in the <code>SyncResolver</code>
50+ * object will be <code>null</code>.
51+ * <P>
52+ * The <code>SyncResolver</code> object may be used to examine and resolve
53+ * each conflict in a row and then go to the next row with a conflict to
54+ * repeat the procedure.
55+ * <P>
56+ * A <code>SyncProviderException</code> object may or may not contain a description of the
57+ * condition causing the exception. The inherited method <code>getMessage</code> may be
58+ * called to retrieve the description if there is one.
