>  
> {code:java}
> DataStream<Integer> dataStream = //...
> CachedDataStream<Integer> cachedDataStream = dataStream.cache();{code}
> The example shows to invoke cache() on a DataStream instance but DataStream class does not have cache() method. The right usage is to call cache() on an instance of DataStreamSource/SideOutputDataStream/SingleOutputStreamOperator.
