Example 1
list:clone(stockSymbols)
This function call takes stockSymbols, a list, as input and creates an identical copy of it. The clone function generates a new list with all elements from stockSymbols in the same order, returning this new list.
Example 2
CREATE STREAM InputListStream (stockSymbols OBJECT);
CREATE SINK STREAM OutputListStream (clonedList OBJECT);
@info(name = 'CloneListStreamWorker')
INSERT INTO OutputListStream
SELECT list:clone(stockSymbols) AS clonedList
FROM InputListStream;
The CloneListStreamWorker handles events from the InputListStream, which includes a list attribute named stockSymbols. It employs the list:clone(stockSymbols) function to generate an identical copy of stockSymbols. The cloned list, maintaining the same order of elements as the original, is output as the clonedList attribute for each event to the OutputListStream.
