 * <ul>
 *   <li>Call {@link #isInitialized()} to verify that all required fields
 *       are set before building.
 *   <li>Parse the message separately using one of the static
 *       {@code parseFrom} methods, then use {@link #mergeFrom(Message)}
 *       to merge it with this one.  {@code parseFrom} will throw an
 *       {@link InvalidProtocolBufferException} (an {@code IOException})
 *       if some required fields are missing.
 *   <li>Use {@code buildPartial()} to build, which ignores missing
 *       required fields.
 * </ul>
 *
 * <p>Note:  The caller should call
 * {@link CodedInputStream#checkLastTagWas(int)} after calling this to
 * verify that the last tag seen was the appropriate end-group tag,
 * or zero for EOF.
