Document Summary

Class diagrams to illustrate classes, interfaces, and their associations, used for static object modeling. Attributes of a classifier is also called structural properties and are shown in several ways: Note symbol is displayed as a dog eared rectangle with a dashed line to the annotated element. Uml not or comment, has no semantic impact. A uml operation is a declaration, with a name, parameters, return types, exceptions list, and possibly a set of constraints of pre and post conditions. Uml method is the implementation of an operation; if constraints are defined, the method must satisfy them. Accessing operations retrieve or set attributes, such as get price and set price. A uml keyword is a textual adornment to categorize a model element. A stereotype represents a refinement of an existing modeling concept and is defined within a uml profile. The stereotype declares a set of tags, using the attribute syntax. A property is a named value denoting characteristics of an element.
