Example of UML Sequence Diagram in Blazor Diagram Component
This UML Sequence Diagram visualizes the step-by-step interactions in a transaction processing system. The process starts with a user initiating a transaction, which is forwarded to a fraud detection system for validation. If the transaction passes the fraud check, it proceeds to completion. Otherwise, it is flagged and canceled, effectively illustrating the conditional control flow in real-world transaction systems.
This example demonstrates how to build a UML Sequence Diagram using the UmlSequenceDiagramModel in the Blazor Diagram component. The diagram model is bound to the SfDiagramComponent through the Model property. Participants in the sequence are defined using UmlSequenceParticipant, where the IsActor property indicates if the participant should be rendered as an actor (stick figure). The UmlSequenceMessage class is used to represent interactions between participants, and its MessageType property defines the type of UML message connector (e.g., synchronous, asynchronous, return). Control flow structures like loops, conditionals, and alternatives are modeled using the Fragments property of UmlSequenceFragment, allowing you to represent complex interactions and behaviors within the sequence.
