Create a Pattern

To create a Design Pattern you first must model the Pattern as a standard UML diagram within Enterprise Architect. The following diagram was created from an example in the GoF book Design Patterns - Elements of Reusable Object-Oriented Software by Gamma et al.

 

ExampleofaGoFPatternDiagram

Access    Select required diagram |  Diagram | Advanced | Save UML Pattern

Reference

On the Save Diagram as UML Pattern dialog, complete the fields as indicated below:

Field/Button

Action

See also

Pattern Name

Type the Pattern name.

 

 

Filename

Type a directory path and .XML filename into which to save the Pattern.

 

 

Category

Type the Category under which the Pattern should be listed in UML Patterns (required).

 

 

Version

Type the Pattern version number.

 

 

Notes

Type any notes on the Pattern.

 

 

Actions

Select the appropriate checkboxes to select the actions for the elements that are contained in the Pattern; these actions are performed when the Pattern is used.

The available actions are:

Create: Creates the Pattern element directly without modification
Merge: Merges the Pattern element with an existing element, enabling the existing element to take on the role of the selected Pattern element
Instance: Creates the Pattern element as an instance of an existing element
Type: Creates the Pattern element types as an existing element

 

If your Pattern includes an Object element, you would use Instance to set the classifier of the Object to one of the Classes in the diagram onto which you are dropping the Pattern.

If your Pattern includes a Property (Port or Part) you would use Type to set the type of the Property to one of the Classes in the diagram onto which you are dropping the Pattern.

 

Use a Pattern

OK

Click on this button twice to save the Pattern.

Once saved you can load the Pattern into Enterprise Architect, into the Resources window.

Notes

In the Corporate, Business and Software Engineering, System Engineering and Ultimate editions of Enterprise Architect, if security is enabled you must have Manage Diagrams permission to save a diagram as a Pattern
If your source diagram contains information flows, the Information Items Conveyed and Information Flows Realized data is not copied into the Pattern
To change the name of one of the elements, double-click on the element to display the Edit dialog; from this dialog you can also add comments detailing the element's purpose
