What is a function call diagram?

A call graph (also known as a call multigraph) is a control-flow graph, which represents calling relationships between subroutines in a computer program. Each node represents a procedure and each edge (f, g) indicates that procedure f calls procedure g. Thus, a cycle in the graph indicates recursive procedure calls.

What is the objective of sequence diagram?

The diagram’s purpose The sequence diagram is used primarily to show the interactions between objects in the sequential order that those interactions occur. Much like the class diagram, developers typically think sequence diagrams were meant exclusively for them.

What is call message in sequence diagram?

A message in a UML sequence diagram specifies the kind of communication, and the sender and receiver. By default, a message is set as a synchronous call. A message can also be a create message or a lost or found message.

What are the use of sequence diagrams in UML?

Uses of sequence diagrams – 1 Used to model and visualise the logic behind a sophisticated function, operation or procedure. 2 They are also used to show details of UML use case diagrams. 3 Used to understand the detailed functionality of current or future systems. 4 Visualise how messages and tasks move between objects or components in a system.

Can a sequence diagram represent a function call?

Sequence diagrams are appropriate to represent function calls, and you can specify the parameters and returned values as well. Communication Diagrams are also an option and tend to go into more detail with regards to parameters used within function calls. This is something I was looking for too.

How is the Unified Modeling Language ( UML ) used?

Unified Modelling Language (UML) is a modeling language in the field of software engineering which aims to set standard ways to visualize the design of a system. UML guides the creation of multiple types of diagrams such as interaction , structure and behaviour diagrams. A sequence diagram is the most commonly used interaction diagram.

How is the message flow represented in UML?

It portrays the communication between any two lifelines as a time-ordered sequence of events, such that these lifelines took part at the run time. In UML, the lifeline is represented by a vertical bar, whereas the message flow is represented by a vertical dotted line that extends across the bottom of the page.
