+ * BackOffStrategy will cause the current thread to sleep for a specific
amount of time. This is used to adhere to
+ * api rate limits.
+ *
+ * The example below illustrates using a BackOffStrategy to slow down
requests when you hit a rate limit exception.
+ *
+ * <code>
+ * public void pollApi(ApiClient apiClient, BackOffStrategy
backOffStrategy) throws BackOffException {
+ * while( apiClient.hasMoreData() ) {
+ * try {
+ * apiClient.pollData();
+ * } catch (RateLimitException rle) {
+ * backOffStrategy.backOff();
+ * }
+ * }
+ * }
+ * </code>
