Where is a Lifeline Creation Occurrence found?

A Lifeline Creation Occurrence is found near the arrowhead of a message that creates a lifeline, which is central to the concept of sequence diagrams in UML (Unified Modeling Language). In the context of sequence diagrams, a lifeline represents an individual participant in the interaction, and it is depicted as a vertical dashed line that extends downwards from the participant's name.

When a message is sent to create a new lifeline, this is represented by an arrow that points towards where the new lifeline will begin. The arrowhead of this message indicates the point of instantiation or creation of the new lifeline. This visualization is essential because it not only shows the flow of messages between participants but also signifies the timing and order in which the participants interact with each other. Understanding where a lifeline creation occurs enhances one's ability to read and understand sequence diagrams effectively.
