org.modelio.metamodel.mmextensions.standard.facilities.interaction.MessageSequencer

public class MessageSequencer
extends java.lang.Object

Service that attributes a sequence number to all messages of an Interaction.

The sequence numbers are computed once on instantiation and won't be updated if the model is modified.

The sequence number is an integer matching the index in the sequence. The sequence order is determined by:

1. The vertical position of the message.
2. When 2 messages have same vertical position they are sorted by name.
3. In last resort they are sorted by identifier.
