Class HistoryUtil

java.lang.Object

ee.telekom.workflow.facade.util.HistoryUtil

public class HistoryUtil
extends Object

Utility class that helps to parse a workflow instance history into a list of human readable steps.

The raw workflow instance history is a compact format that enlists a series of execution events separated by a "|". Please refer to Event to understand the syntax and meaning of individual events.

For instance, this class parses the following series of events
"start|1:1!|1:1=>2|1:2!|2:2=>3|3:2=>4|2:3!|2:3=>-2|2:-2!|1:-2=>6|1:6!|executed|"
into
"start; token 1 executed node(s) 1, 2; token 2 moved from 2 to 3; token 3 moved from 2 to 4; token 2 executed node(s) 3, -2; token 1 moved from -2 to 6; token 1 executed node(s) 6; execution completed"
