Search values in list with streaming api and keep search position (normalize measurement data)

QUESTION

Search values in list with streaming api and keep search position (normalize measurement data)

Asked 2018-Jul-12 at 23:45

I get lists of measurement data. An entry in this list contains a timstamp and the data itself. There is more or less for every 15min an entry - but there may also be missing data points or a big jitter. What I need is to build a normalized list of data, where I have an entry for exact every 15min. As data, I can just take the previous measurement.

Input:

...

Below is some sample code to show how you can achieve filling in the missing data points.

A lot of the code below is not required as it's just setting up data to show case how the code actually works.

What the code does is use the Stream API collect functionality and compare the last collected DataPoint with the current DataPoint and insert a new entry if the difference between there timestamps is greater than 15 minutes.

As you can see from the test data there is a 30 minute difference between C and D as well as E and F. This means data for C and E will be replicated.
