Links represent data flow and direct the sequence in which
the processing of the activities in your snippet occurs.
About this task
You can either create a link automatically when your drop
an object onto the canvas as described in the first step, or link
two existing objects as described in the second.
Procedure
- Create a link automatically in either of these ways:
- Click an Input in the tray, and
drag it onto an input terminal of an existing activity on the canvas,
or
- Click an item in the palette, and then click a valid
input or output terminal of an existing activity on the canvas.
The crossed out circle on your cursor will disappear when the
terminal is a valid choice for a link.
- Link two existing objects on the canvas as follows:
- Drop an activity onto the canvas.
If it can
take an incoming link, it will have a triangle on its left edge

.
If it can take an outgoing link, the triangle will be on the right
edge

.
- Move the cursor over an outgoing link until the yellow
circle appears as shown in this image.
- Click the yellow circle.
The cursor will
change appearance, and will look like a plus sign with a crossed out
circle beside it.
- Drag the cursor out over the canvas.
A yellow
string is now attached to the cursor, and when you hover over a valid
incoming link icon, the crossed out circle disappears.
- Click the activity that you want to link to.
The
link becomes a solid gray line and connects the two activities.
- To change the target activity, click the link so that
it becomes highlighted, click the black box at the target end of the
link, and drag it to a new incoming link.
