Combined Fragment
Inserting sequence diagram elements
Combined Fragment
Combined fragments are subunits, or sections of an interaction. The interaction operator
visible in the pentagon at top left, defines the specific kind of combined fragment. The constraint
thus defines the specific fragment, e.g. loop fragment, alternative fragment etc. used in the
interaction.
The combined fragment icons in the icon bar, allow you to insert a specific combined fragment:
seq, alt or loop. Clicking the interactionOperator combo box, also allows you to define the
specific interaction fragment.
Interaction Operators
Weak sequencing seq
The combined fragment represents weak sequencing between the behaviours of the operands.
