Reverse Java source to sequence diagram

Visualize interactions between Java objects by reverse Java source code to standard UML sequence diagram.

Tutorial

• Reverse engineering sequence diagram from Java source code

Generate executable PHP Doctrine object relational mapping (ORM) layer from standard UML class diagram and entity relationship diagram.

Instant code generation

Generate UML class diagram to 15 programming languages. Supported programming languages include Java, C#, VB.NET, PHP, ODL, Action Script, IDL, C++, Delphi, Perl, XML Schema, Python 2.6, Objective-C, Ada 95 and Ruby.

The Instant Code Generator employs the Apache Velocity template engine to perform code generation. User can customize the template engine to generate code in their own code style easily.

Reverse engine 12 programming languages to UML class diagram. Supported programming languages include Java, C++, .NET DDL or exe, IDL, Ada 95, XML, XML schema, JDBC, Hibernate, PHP 5.0 or above, Python and Objective-C. The latest version supports reversing source code to package diagram for high level analysis.
The following movie demonstrates how to reverse source code using instant reverse.

Smart Development Environment for Eclipse generates state machine code from UML state machine diagram to Java, C#, VB.NET and C++. The following movie demonstrates how to generate state machine code.

State machine diagram code generation

Step 1 of 7: Model the controller class

Model the controller class in class diagram, with the required operations added.

Step 2 of 7: Add a sub state machine diagram

Move the mouse cursor over the controller class, move to the resource icon at the bottom right, click on it and add a state machine diagram as sub-diagram of the controller class.

Step 3 of 7: Complete the state machine diagram

Model the state machine with state machine diagram. Both the states and transitions should be modeled accurately.

Step 4 of 7: Pick up operation for transitions

Open the transitions' specifications, and select the corresponding operations. Those operations are offered by the controller class.

Step 5 of 7: To generate state machine code

Select Modeling > State Machine Code > Generate Code... from the main menu to generate state machine code.

Step 6 of 7: Confirm code generation options

Configure other options if needed. Click OK when ready.

Step 7 of 7: Using the generated code

The generated state machine code can be compiled and executed. You may run the sample application generated alongside to examine the effect of state transition. As a side note, you may also model an application with class diagram, generate code with Instant Generator, implement the generated code by calling the state machine code generated.

Database generation

Smart Development Environment for Eclipse supports generating database schema (DDL) from entity relationship diagram. Smart Development Environment for Eclipse supports all major database vendors. You can generate full database initialization scripts of alter statements just for updating existing databases. The following movie shows you the database generation feature.

Generate Java object-relational mapping layer for existing DB

Smart Development Environment for Eclipse supports generating Java ORM code for accessing relational database. The following movie demonstrates how to reverse existing database to ERD, synchronize ERD to UML class diagram, and generate Java ORM code to access database.

Generate DB and Java code

Smart Development Environment for Eclipse supports generating both database schema (DDL) and Java ORM code for accessing databases. There are various options to configure the generated code and databases. The following screenshots outline the steps involved.

Generate DB and Java code

Step 1 of 7: Get ready for object and data model

Model the system with class diagram (with ORM Persistable classes) and produce the entity relationship diagram (ERD) through synchronization, or the other way round. Make sure the object model is synchronized with the data model.

Step 2 of 7: To generate code and database

Select Modeling > ORM > Generate Code... from the main menu to generate ORM Java code.

Step 3 of 7: Confirm code generation settings

Confirm code generation settings such as the way to handle error, the persistent API such as Factory, DAO, POJO, etc.

Step 4 of 7: Configure database

Select Database tab. After that, select Export to database, and configure the target database. After all, click OK to start generating code and database.

Step 5 of 7: Setup development environment

Refresh the Java project node to gain access to the generated files, and add the lib/orm.jar to project build path.

Step 6 of 7: Develop application

Develop the application through the use of the ORM classes. You may learn the usage of generated files by reading the sample files generated to the ormsamples folder.

Step 7 of 7: Execute the code

Run the code, enjoy!
