  software on any level
• Ability to visually explore your software
• Review software metrics and source
• Automatically creates design documents
• Spend more time engineering
• Get new hires on board faster
• Reduces the cost of software maintenance

UML Diagrams

UML Diagrams

• Class Diagram
• Unified Modeling Language notation
• Classes
• Classs members
• Class Hierarchy
• Can add relevant detailed member-level
  relationships (associations)

10
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

11
UML Diagrams

• Built-In Abstractions
• One mechanism to address the problem of scope.
• abstracting member to member relationships to the
  members containers
• example, if classAmethodA calls
  classBmethodB, 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

12
Control Flows
13
Control Flow Analysis

• Control Flow mode provides the next level of
  detail beyond a call graph
• Shows the order that all the function calls are
  made
• See where a call is made all the time or just
  under some conditions
• Able to accurately understand the dependencies in
  complex or sequence critical code

14
Flow Charts

• Shows the complete control flow, or program logic
  occurring in each function
• Helps you quickly grasp the internal logic of a
  routine
• Sorts through if conditions, switch statements,
  and do loops
• Linked to the File Editor so changes can be made
  quickly and easily
• By seeing the source code in combination with the
  logic, you're able to understand and modify the
  function much more quickly and accurately

15
Function Pointer Support

• Any variable with data containing function names
  is marked as a function pointer
• All functions are recorded as being potentially
  called from a function pointer
• If a function makes a call through the function
  pointer, then the function is shown as calling
  the function pointer variable

16

• You can see the potential call tree by following
  the call relationship from the function to the
  function pointer variable
• The result is that you end up with a complete and
  accurate understanding of your software.

Software Metrics and Design Documents
18
Software Metrics

• Use to analyze all the measurements taken by
  Imagix 4D
• Can list, sort, compare, and rank all files,
  classes, functions, and variables
• Has many different general categories
• Lines of Source Code
• Lines of Comments
• Comments to Code Ratio
• Number of Variables in a File
• Number of Declarations in a File
• Etc.

19
Software Metrics

• Also, has many specific categories
• Halsteads Metrics
• Mental Effort, Program Difficulty, and
  Intelligence Content
• Inherited and Derived Classes
• Class Coupling
• Lack of Cohesion Between Classes
• McCabe Cyclomatic Complexity
• Etc.

20
Software Metrics

• Display in different formats Absolute,
  Relative, and Graph
• Can also change the thresholds of the data found

21
Documentation Using Imagix

• Five to Fifteen percent of development goes into
  documentation
• Imagix automates the system by using the data
  gathered and the source code
• Outputs into three formats
• ASCII
• RTF (Rich Text Format)
• HTML

22
Documentation Using Imagix

• Sorted into nine categories
• Project
• Files
• Classes
• Functions (also Library)
• Macros
• Variables
• Types (also Pre-Defined)
