UML Diagrams

Class Diagram•Unified Modeling Language notation

•Classes

•Class’s members

•Class Hierarchy

• Can add relevant detailed member-level relationships (associations)

UML Diagrams

File Diagram•Same UML diagram format as the class diagrams

•Displaying package / member information at the file level

•physical location of the files

•Add in build dependencies

UML Diagrams

Built-In Abstractions •One mechanism to address the problem of scope.

•abstracting member to member relationships to the members‘ containers

•example, if classA::methodA calls classB::methodB, you're able to view a higher level graph where classA is shown as calling classB. You thereby can avoid becoming deluged in the details of the design

Control FlowsControl Flows

Control Flow AnalysisControl Flow Analysis

Control Flow mode provides the next level Control Flow mode provides the next level of detail beyond a call graphof detail beyond a call graph

Shows the order that all the function calls Shows the order that all the function calls are madeare made

By seeing the source code in combination with By seeing the source code in combination with the logic, you're able to understand and modify the logic, you're able to understand and modify the function much more quickly and accuratelythe function much more quickly and accurately

Function Pointer SupportFunction Pointer Support

Any variable with data containing function Any variable with data containing function names is marked as a function pointernames is marked as a function pointer

All functions are recorded as being All functions are recorded as being potentially called from a function pointerpotentially called from a function pointer

If a function makes a call through the If a function makes a call through the function pointer, then the function is shown function pointer, then the function is shown as calling the function pointer variableas calling the function pointer variable

You can see the potential call tree by You can see the potential call tree by following the call relationship from the following the call relationship from the function to the function pointer variablefunction to the function pointer variable

The result is that you end up with a The result is that you end up with a complete and accurate understanding of complete and accurate understanding of your software.your software.
