Found Message
A Found Message in a UML Sequence Diagram represents a message that comes from an unknown or unspecified source outside the scope of the interaction. In Modeldraw, you can use Found Messages to show events or triggers that initiate a sequence of interactions from an external source.
Understanding Found Message
A Found Message represents an interaction that originates from an unknown or unspecified sender. Key characteristics include:
It shows a message coming from outside the scope of the current diagram
It is drawn as a solid line with a filled arrowhead, starting from a filled circle
It typically triggers the start of an Activation Bar on the receiving Lifeline
It has no visible sender Lifeline
A Found Message is represented in UML by a solid line with a filled arrowhead, originating from a filled circle.
Found Messages are crucial in Sequence Diagrams for:
Representing external events or triggers
Showing the initiation of a sequence from an unknown source
Indicating interactions that start outside the current scope of the diagram
Creating a Found Message
To create a Found Message in Modeldraw:
Select the Found Message tool from the toolbox.
Click on the Activation Bar of the receiving Lifeline where you want the message to end.
The Found Message will be automatically created, starting from a filled circle and ending at the specified point on the Activation Bar.
