Advanced diagram editing and zoom. Built-in design critics provide unobtrusive review of design and suggestions for improvements. Extensible modules interface. OCL support. Forward engineering (code generation supports C++ and C#, Java, PHP 4, PHP 5, Ruby and, with less mature modules, Ada, Delphi and SQL). Reverse engineering / JAR/class file ...
C++ Java and C# class headers are synchronized between diagrams and code in real-time Programmer's workbenches, documentation tools, version control systems Supports following UML diagrams: Use case diagram, Sequence diagram, Collaboration diagram, Class diagram, Statechart diagram, Activity diagram, Component diagram, Deployment diagram and ...
This will invoke a Java method, and does the same thing as object. method (argument,...) in Java. An object's fields can be accessed with: object:field-name or (invoke object 'field-name). Static (class) methods can be invoked with the function invoke-static. Kawa can be extended with Java code (by creating scheme functions in Java), and ...
A class diagram exemplifying the singleton pattern. In object-oriented programming, the singleton pattern is a software design pattern that restricts the instantiation of a class to a singular instance. It is one of the well-known "Gang of Four" design patterns, which describe how to solve recurring problems in object-oriented software. [1]
Integer are reference objects, on the surface no different from List, Object, and so forth. To convert from an int to an Integer, one had to "manually" instantiate the Integer object. As of J2SE 5.0, the compiler will accept the last line, and automatically transform it so that an Integer object is created to store the value 9. [2]
NClass supports only class diagram of the standard UML diagram types. The user interface is designed to be simple and user friendly, and the visualization of diagrams is configurable via a style system. NClass can generate source code from the model or reverse engineer .NET assemblies by a plugin written by Malte Ried.
Python: the built-in int (3.x) / long (2.x) integer type is of arbitrary precision. The Decimal class in the standard library module decimal has user definable precision and limited mathematical operations (exponentiation, square root, etc. but no trigonometric functions). The Fraction class in the module fractions implements rational numbers ...
UML class diagram that illustrates forwarding. In this Java example, the Printer class has a print method. This print method, rather than performing the print itself, forwards to an object of class RealPrinter. To the outside world it appears that the Printer object is doing the print, but the RealPrinter object is the one actually doing the work.
