Reconnecting Objects
Some of the objects that are managed by the MSC Editor can be reconnected:
- Reconnecting a Comment Symbol
- Reconnecting a Condition or MSC Reference Symbol
- Reconnecting a Message
- Reconnecting a Message-to-self
- Redirecting a Message.
- Reconnecting a Process Create
Reconnecting a Comment Symbol
A comment symbol can be reconnected to a different object or disconnected completely from all objects.
- Drag the comment symbol connection handle towards the new connection point. The existing connection line is erased and a new line that follows the position of the mouse pointer is drawn.
- Click the connection point on the new object. The connection line is fixed to the new object.
Disconnecting the Comment Symbol
Reconnecting a Message
You can reconnect the base or the end of a message to another instance axis:
- Drag the base or end of the message towards the desired instance axis. As soon as you move the mouse the message is unconnected.
- When the mouse pointer is close to the new instance axis, release the mouse button. The message is now reconnected.
Reconnecting a Message-to-self
You can reconnect the base or end of a message-to-self to another instance axis. This changes the message-to-self to an ordinary message.
- Drag the end (or the base) of the message-to-self away from the instance axis. As soon as you move the mouse, the line is displayed as an ordinary message line. Continue dragging the end of the line up or down to the new connection point and release the mouse button.
Redirecting a Message
When you draw a message, the message goes from the source instance to the target instance. It is possible to redirect a message (i.e. change its direction):
- Select the message to redirect.
- Select the Redirect command on the Edit menu. The message is redrawn in the opposite direction, and the text attributes are positioned accordingly.
Messages-to-self and overtaken messages cannot be redirected.
In Figure 348 two messages are shown. The message sent first is consumed after the message sent last, i.e. it is overtaken.
Reconnecting a Condition or MSC Reference Symbol
To connect or disconnect instances to the symbol:
- Use the Connect dialog on the Edit menu, see Connect. (Remember, at least one instance must be left connected.)
Reconnecting a Process Create
You can reconnect the base of a process create from one instance axis to another in a similar way as when reconnecting a message (see Reconnecting a Message).
