/**
 * Reserved for internal use. Writes an entity to the specified <code>JsonGenerator</code> as a JSON resource
 * //from w w w .  ja  v  a 2  s .  c om
 * @param generator
 *            The <code>JsonGenerator</code> to write the entity to.
 * @param options
 *            The {@link TableRequestOptions} to use for serializing.
 * @param entity
 *            The instance implementing {@link TableEntity} to write to the output stream.
 * @param isTableEntry
 *            A flag indicating the entity is a reference to a table at the top level of the storage service when
 *            <code>true<code> and a reference to an entity within a table when <code>false</code>.
 * @param opContext
 *            An {@link OperationContext} object used to track the execution of the operation.
 * 
 * @throws StorageException
 *             if a Storage service error occurs.
 * @throws IOException
 *             if an error occurs while accessing the stream.
