Unified Modeling Language (UML, also known as the Unified Modeling Language or standard modeling language) is an international object management organization OMGand visual modeling language standards. can be used to describe narrative (specify), visualization (visualize), structuring (construct) and documenting (document) software-intensivethe various workpieces of the type system (artifacts,

1. emergence of standard modeling language UML The accepted object-oriented modeling language appeared in the middle of 1970s. From 1989 to 1994, the number has increased from 10 to more than 50. Among the many modeling languages, language creators strive to promote their own products and improve them in practice. However, users of the OO method do not understand the advantages and disadvantages of different modeling languages and their differences.

longer any overlapping of color blocks in the graph (the overlap generated by asynchronous calls is not counted), and both Stop () and EventHandler return (asynchronously), eliminating the existence of deadlocks. This is why andriod designed asynchronous message processing mechanisms for Looper, MessageQueue and Handler, and is used extensively in the framework, because Android is an extremely complex multi-threaded/multi-process application environment, Locking-based synchronous invocation me

. examples ). In UML 2, a component is drawn as a vertical rectangle stacked with small pieces. In UML 2, a high-level abstract view of a component can be modeled using a rectangle, including the component name and the text and/or icons of the component prototype. The component prototype text is "«component>", and the component prototype icon is a large rectangle with two protruding small rectangles on the

Author: zyl910I. background Currently, many commonly used UML tools do not support objective-C, which is inconvenient to draw UML. You must manually convert the objective-C syntax parameter list to the UML or C ++ syntax. It is laborious and error-prone.So I want to write a tool that automatically converts the paramete

. An asynchronous message is similar to a synchronous method, but the line drawn by the message carries a single stick, as shown in figure 6. Figure 6: sequence diagram fragment of asynchronous messages passed to entity 2 ConstraintsWhen modeling the interaction of an object, messages are transmitted to the object only when a condition is met. Constraints are used in various UML diagrams for control flow. Here, I will discuss the constraints of

plantuml--Simple and fast UML editing software for EclipseIntroduction: in the application system software development process, if the software is composed of many objects, its structure is difficult to clarify by virtue of analysis, at the same time in order to facilitate the development and reuse of software, so in the development of the system before the modeling is very necessary, in a number of modeling methods to choose one to adapt to their own

The development of Object-Oriented Analysis and Design (OOA D) methods has seen a climax from the end of 1980s to the end of 1990s. UML is the product of this climax. It not only unifies the Expression Methods of booch, Rumbaugh, and Jacob, but also makes further development on it, and finally unified it into the standard modeling language accepted by the masses. 1. emergence of standard modeling language UMLThe accepted object-oriented modeling lang

the class and the relationship between classes are displayed more clearly. Figure 1: General UML relationships The extends keyword in Java declares the inheritance relation, which is equivalent to the "generalization" (also translated as "generalization") Relation in UML. In UML graphics, the subclass is represented by a solid-line closed arrow of t
