In capsule-based structure diagrams, you can create a port to define
an interaction point between a capsule and the environment. A port specifies
the events that a capsule acts on. You can add a port inside or on the border
of a structure diagram.
About this task
A port that is on the border and has public visibility is visible
externally, which means that it is part of a capsule's public interface. A
port that is inside a structure diagram is not visible outside the capsule
because it is not part of the capsule's public interface.
To
create a port:
Procedure
- In the Project Explorer view, right-click
a capsule; then click Open Structure Diagram.
- In the Palette, click Port.
- In the diagram editor, click where you want to create a port.
- Select one of the following options:
- To bind a port to a new protocol, click Create protocol ,
type a name for the port, and click OK.
- To bind a port to an existing protocol, click Select existing
element. In the Select Element dialog box,
select a protocol and click OK.
Results
Tip: To quickly add a port from the Project
Explorer view or diagram editor, right-click a capsule; then click . You
can also create a port by dragging a protocol class from the Project
Explorer view to the border or interior of a structure diagram.
The type of the port that you create depends on the protocol component that
you drag.
