Both sequence diagrams and collaboration diagrams are kinds of interaction diagrams. The interaction operator opt means that the combined fragment represents a choice of behavior where either the (sole) operand happens or nothing happens. state diagram (state machine diagram or statechart diagram): A state diagram, also called a state machine diagram or statechart diagram, is an illustration of the states an object can attain as well as the transitions between those states in the Unified Modeling Language (UML).

So, an “opt” fragment type with no further “else” conditions. opt: creates We form the graph by getting the information from sequence diagram to form the node contain id, message name, message target, message number, operand status. The condition that describes may range from some deterministic calculation ( 2+2==4 ) to user choice ( red pill selected ) to random event ( atom decays ). UML Sequence Diagram: Interaction Fragment (Alt, Opt, Par, Loop, Region) A common issue with sequence diagrams is how to show conditions and iterations. Any guidance appreciated.

A sequence diagram is an interaction diagram that emphasizes the time-ordering of messages. Objects take on the responsibility for things like managing data, moving data around in the system, responding to inquiries, and protecting the system. An option is semantically equivalent to an alternative combined fragment where there is one operand with non-empty content and the second operand is empty. A destructor message destroys its receiver.
