Adding a link to a snippet

Links represent data flow and direct the sequence in which the processing of the activities in your snippet occurs.

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

1. Create a link automatically in either of these ways:

   1. Click an Input in the tray, and drag it onto an input terminal of an existing activity on the canvas, or

   2. 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.
2. Link two existing objects on the canvas as follows:
   1. 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 .

   2. Move the cursor over an outgoing link until the yellow circle appears as shown in this image.

      

   3. Click the yellow circle. The cursor will change appearance, and will look like a plus sign with a crossed out circle beside it.

   4. 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.

   5. Click the activity that you want to link to. The link becomes a solid gray line and connects the two activities.

   6. 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.
