In software engineering, a class diagram [1] in the Unified Modeling Language (UML) is a type of static structure diagram that describes the structure of a system by showing the system's classes, their attributes, operations (or methods), and the relationships among objects. The class diagram is the main building block of object-oriented modeling.
In UML, become is a keyword for a specific UML stereotype, and applies to a dependency (modeled as a dashed arrow). Become shows that the source modeling element (the arrow's tail) is transformed into the target modeling element (the arrow's head), while keeping some sort of identity, even though it may have changed values, state, or even class.
A UML link is run-time relationship between instances of classifiers, while a dependency is a model-time relationship between definitions. A typical uni-directional link requires the one instance to know about, and thus depend, upon the other, but this is not required.
Class diagram - a type of static structure diagram that describes the structure of a system by showing the system's classes, their attributes and the relationships between the classes. Classifier - a category of UML elements that have some common features, such as attributes or methods.
The UML notation and semantics are really geared toward computerized UML tools. A UML state machine, as represented in a tool, is not just the state diagram, but rather a mixture of graphical and textual representation that precisely captures both the state topology and the actions.
A directed graph. A classic form of state diagram for a finite automaton (FA) is a directed graph with the following elements (Q, Σ, Z, δ, q 0, F): [2] [3]. Vertices Q: a finite set of states, normally represented by circles and labeled with unique designator symbols or words written inside them
Class diagram - A class diagram is a type of static structure UML diagram that describes the structure of a system by showing the system's classes, its attributes, and the relationships between the classes. The messages and classes identified through the development of the sequence diagrams can serve as input to the automatic generation of the ...
As you can see from the Class Diagram on the right a car "has-a" carburetor, or a car is "composed of" a carburetor. When the diamond is coloured black it signifies composition , i.e. the object on the side closest to the diamond is made up of or contains the other object.
