| <div class="block">StreamletShadow is a special kind of StreamletImpl object: |
| - It is still an StreamletImpl therefore it supports all Streamlet functions like filter() |
| and map(), and can be the parent object of other StreamletImpl objects. Therefore, |
| from API point of view, it can be used in the same way as a normal StreamletImpl object. |
| - However it is just an shadow object of a real StreamletImpl object and it doesn't |
| represent a node in the topology DAG. Therefore it can not be a child of another StreamletImpl |
| object. As the result, the shadow object is clonable, and it is fine to create multiple |
| StreamletShadow objects pointing to the same StreamletImpl object and have different properties. |
| |
| A StreamletShadow object can be used to decorate the real Streamletimpl object. This is |
| important for children StreamletImpl objects to consume output data from the same parent in |
| different ways, such as selecting different stream. |
| |
| Usage: |
| To create a shadow object that selecting "test" stream from an existing StreamletImpl |
| object(stream): |
| |
| StreamletImpl shadow = new StreamletShadow(stream) { |
| Override |
| public String getStreamId() { |
| return "test"; |
| } |
