What is Objectaid Sequence Diagram?




Objectaid Sequence Diagram is an Eclipse plug-in that can generate class diagrams from your source code. A class diagram is a type of UML diagram that shows the structure of a system by depicting its classes, attributes, methods, and relationships among them. Class diagrams are useful for visualizing and documenting the design of a system, as well as for reverse engineering existing code.


A brief introduction to Objectaid Sequence Diagram




Objectaid Sequence Diagram was created by Felix Mayer, a software engineer who wanted to make UML diagramming easier and faster for developers. He launched Objectaid in 2009 as a commercial product that offered two types of diagrams: class diagrams and sequence diagrams. A sequence diagram is another type of UML diagram that shows the interactions between objects in a system over time. However, in March 2022, Mayer passed away in a tragic accident, and his website objectaid.com went offline shortly after. This left many users of Objectaid wondering how to download, install, and activate their licenses for the plug-in.


The benefits of using Objectaid Sequence Diagram




Objectaid Sequence Diagram has many benefits for developers who want to create class diagrams from their source code. Some of these benefits are:



  • It is easy to use: You can simply drag and drop classes from your project explorer or package explorer into the diagram editor, and Objectaid will automatically create a class diagram for you. You can also customize the appearance and layout of your diagram with various options and settings.



  • It is fast: You can generate class diagrams from your source code in seconds, without having to manually draw or edit them. You can also update your diagrams automatically whenever you change your code.



  • It is accurate: You can trust that your diagrams reflect the actual structure and relationships of your code, as Objectaid uses reflection and bytecode analysis to extract information from your classes.



  • It is compatible: You can use Objectaid with any version of Eclipse that supports Java development tools (JDT), from Eclipse 3.x to Eclipse 2022-03 (4.23.0). You can also export your diagrams as image files (PNG or JPG) or vector graphics files (SVG) that can be used in other applications.



The features of Objectaid Sequence Diagram




Objectaid Sequence Diagram has many features that make it a powerful tool for creating class diagrams from your source code. Some of these features are:

  • It supports multiple types of modifiers: You can show visibility (public, private, protected), staticness (static), abstractness (abstract), finalness (final), etc.



  • It supports multiple types of annotations: You can show stereotypes (>, >, >, etc.), constraints (invariant, precondition, postcondition, etc.), comments (// comment), etc.



  • It supports multiple types of filters: You can filter out classes or relationships based on their names or patterns.



  • It supports multiple types of layouts: You can arrange your classes or relationships automatically or manually.



  • It supports multiple types of customizations: You can change the colors, fonts, sizes, shapes, styles, etc. of your classes or relationships.

How to use Objectaid Sequence Diagram to generate class diagrams from source code?




Once you have installed Objectaid Sequence Diagram successfully in 2022, you can start using it to generate class diagrams from your source code. Here are some basic steps to create and edit class diagrams with Objectaid Sequence Diagram:


The basics of class diagrams and UML notation




A class diagram is a type of UML diagram that shows the structure of a system by depicting its classes, attributes, methods, and relationships among them. UML stands for Unified Modeling Language, which is a standard way of visualizing and documenting software systems.


A class diagram consists of several elements, such as:



  • A class: A class is a rectangle with three compartments: the top compartment shows the class name, the middle compartment shows the attributes (fields or variables) of the class, and the bottom compartment shows the methods (functions or operations) of the class.



  • A relationship: A relationship is a line that connects two classes and shows how they are related to each other. There are different types of relationships, such as inheritance (a solid line with a hollow triangle), association (a solid line with an optional name and multiplicity), aggregation (a solid line with a hollow diamond), composition (a solid line with a filled diamond), dependency (a dashed line with an open arrow), realization (a dashed line with a hollow triangle), usage (a dashed line with an open arrow), implementation (a dashed line with a hollow triangle), generalization (a solid line with a hollow triangle), specialization (a solid line with a hollow triangle), etc.



  • A modifier: A modifier is a symbol or word that shows some additional information about a class or a relationship, such as visibility (+ for public, - for private, # for protected), staticness (underlined), abstractness (italicized), finalness (final), etc.



  • An annotation: An annotation is a label or note that shows some extra information about a class or a relationship, such as stereotypes (>, >, >, etc.), constraints (invariant, precondition, postcondition, etc.), comments (// comment), etc.



The steps to create and edit class diagrams with Objectaid Sequence Diagram




To create and edit class diagrams with Objectaid Sequence Diagram, you can follow these steps:



  • Create a new diagram file by going to File > New > Other > ObjectAid UML Diagram > Class Diagram. Give it a name and location and click Finish.



  • Add classes to your diagram by dragging and dropping them from your project explorer or package explorer into the diagram editor. You can also right-click on your diagram editor and select Add From Project or Add From Jar File to add classes from your project or external libraries.



  • Add relationships to your diagram by dragging and dropping them from the palette on the right side of your diagram editor onto the classes that you want to connect. You can also right-click on your diagram editor and select Add Relationship to add relationships manually.



  • Edit your classes and relationships by selecting them and changing their properties in the properties view on the bottom right corner of your diagram editor. You can also double-click on them to edit their names or labels directly in the diagram editor.



  • Customize your diagram by changing its appearance and layout using the options and settings in the toolbar above your diagram editor. You can also right-click on your diagram editor and select Format Graph or Layout Graph to apply automatic formatting or layout algorithms to your diagram.



  • Save your diagram by going to File > Save or pressing Ctrl+S. You can also export your diagram as an image file (PNG or JPG) or a vector graphics file (SVG) by going to File > Export > Other > ObjectAid UML Diagram > Image File or Vector Graphics File.



The best practices and tips for using Objectaid Sequence Diagram effectively




To use Objectaid Sequence Diagram effectively, you can follow these best practices and tips:



  • Use meaningful names for your classes and relationships that reflect their roles and responsibilities in your system.



  • Use appropriate modifiers and annotations for your classes and relationships that show their visibility, staticness, abstractness, finalness, stereotypes, constraints, comments, etc.



  • Use appropriate types of relationships for your classes that show their inheritance, association, aggregation, composition, dependency, realization, usage, implementation, generalization, specialization, etc. Use different types of lines and symbols to show the different types of relationships.



  • Use appropriate levels of abstraction and detail for your class diagrams. Don't include too many classes or relationships that are irrelevant or trivial for your purpose. Don't omit important classes or relationships that are essential for your purpose. Use packages or sub-diagrams to group related classes or relationships and reduce clutter.



  • Use consistent and clear naming conventions for your classes and relationships. Follow the standard naming rules for Java classes and methods. Use meaningful and descriptive names that reflect the roles and responsibilities of your classes and relationships.



  • Use comments and notes to explain any ambiguous or complex aspects of your class diagrams. You can use annotations or separate text boxes to add comments and notes to your class diagrams. Use simple and concise language that can be understood by your audience.



  • Validate and verify your class diagrams with your stakeholders and team members. Make sure that your class diagrams accurately represent the structure and behavior of your system. Make sure that your class diagrams are consistent with other UML diagrams or documentation of your system. Make sure that your class diagrams are clear and easy to understand by your audience.
