Stringified Value Format

QPR ProcessAnalyzer uses the stringified value format in several places when filters are defined using the JSON format. The stringified format encodes data of different types into a string format (which is supported by JSON format).

The stringification is done according to following rules:

Data type	Prefix	Format	Example
string	0	0<string value>	Patricia White -> 0Patricia White
decimal number	1
date	2	2yyyy-MM-ddTHH:mm:ss.fff	1st of July 2018 -> 22018-07-01T00:00:00.000 12th of October 2021 at 08:34 -> 22021-10-12T08:34:00.000
null value	3	3 (means null value)
Small integer	4
Large integer	5
boolean	6	6True or 6False
timespan	7	7d.HH:mm:ss.fff	2 days -> 72.00:00:00.000 6 hours -> 70.06:00:00.000 1.3 seconds -> 70.00:00:01.300
