XOR-Split Gateway (Exclusive Gateway)

Capture

Notes

• The conditional expression is evaluated in the order of the list, and proceeds only to the transition destination that is first determined to be true
• If none of the conditional expressions are true, it will proceed to the [Default flow]
  • The [Default flow] is marked with a diagonal line on the flow
• Each row can contain multiple conditional expressions
  • Token moves to the specified destination only if all the conditions are satisfied
  • You can configure AND conditions using this
• You can specify the same destination to different rows of condition
  • Token moves to the specified destination if either of the conditions are satisfied
  • You can configure OR conditions using this
• To unify the split paths back into a single path, place a Merge Gateway (XOR)
• Spring Expression Language (SpEL) can be specified in the Split Condition settings
  • This is an advanced feature for engineers
  • E.g. #q_string?.startsWith(‘[test]’), or #q_datetime < #now.addDays(-1)
  • When processInstanceDebug == true is specified, the transition will occur only during debug execution
