Class Modelling

The UMLGraph class diagrams allows you to model All relationship tags appart from @extends take four arguments:
  1. The source adornments (role, multiplicity, and visibility)
  2. The relationship name
  3. The target adornments (role, multiplicity, and visibility)
  4. The target class
Arguments can be space-separated, or enclosed in quotes if they need to contain the space character. The - character is used as a placeholder to denote empty arguments. You can use the \n sequence to separate the first three adornments in separate centered lines; the \l and \r sequences can also be used to generate left and right aligned lines. You can use the < and > characters in the relationship name to enclose stereotype names. These will be automatically enclosed in guillemots. Note that a relationship's target class is not implicitly defined; it should also be specified using the Java class syntax. The target can be specified by simple name, java class lookup rules (imports and visibility) will be used to determine the actual class. The following is an example of a relationship specification and the resulting UML diagram: 
class Tyre {}
class Engine {}
class Body {}

/**
 * @composed 1 - 4 Tyre
 * @composed 1 - 1 Engine
 * @composed 1 - 1 Body
 */
class Car {}
