APPENDIX B
UML 2.0 Notation Guide
Class Diagram Notation
The Class diagram notation is explained fully in Chapters 5 through 7.
Class notation
Attribute declaration
[visibility] [/] name [:type] [multiplicity] [‘=’default]
[‘{‘property-string’}’]
The optional underline defines a class-level attribute.
- isDerived: The default value is false.
- isReadOnly: The default value is false.
Operation declaration
[visibility] name ([parameter-list]) ‘:’ [return-result]
[‘{‘property-string’}’]
The optional underline defines a class-level attribute.
Tagged value declaration
Valid class presentations
Classes may be identified with a name and optional stereotype. The stereotype may be in text or icon form.
Figure B-2: Four presentation alternatives for classes with stereotypes.
Interface class notation
Figure B-3: Interface class notation.
Template class
Parameter syntax
template-parameter ::= parameter-name
[ ‘:’ parameter-kind][‘>’ constraint]
[‘=’ default]
parameter-kind ::=
‘class’ | ‘component’ | ‘type’ | ‘interface’ |‘signal’
|‘value’ |‘operation’ |‘attribute’ |‘part’ |‘class’
| parameter ::= parameter-name | operation-name
( parameter-list )
constraint ::= [‘{contract }’] classifier-name
default ::= classifier-name | expression | attribute-name
| part-name | operation-name
If the parameter-kind is omitted, then parameter-kind is ‘class’.
Bound element syntax
template-name ‘<’ value-list ‘>’
