Decisions & Control

There are several nodes that control the flow to implement logic. You can control the flow and its properties by using the nodes below.

Decision

• delay : slows down the messages passing through a flow
  • by fixed delay
  • by random delay
  • by delay with 'msg.delay' value
• trigger : send a message
  • after a defined time
  • when it be reset
  • at regular interval
• switch : route a message based on a context value
• split : split text into one message
  • per line
  • per specific delimiter
• join : combine texts into a single block of text
  • automatically
  • using specific delimiter
• change : Set a message property to a fixed value
• range : Map a property between different numeric ranges
