Detailed information

Although the construction of a subsystem hierarchy makes the subject software easier to understand, it also hides many low-level details.

To view information on the immediate neighborhood around the ListADT subsystem node as it is presented within a window:

1. Choose View Information from the Node menu\ of the ListADT subsystem node.

   A textual Information window appears, presenting information about ListADT (in the window just activated).

   

   This information includes the node's:

   • internal node ID,
   • node type,
   • incoming and outgoing arcs by arc type, and
   • neighboring nodes along these arcs (with their node name and type).
   Some of this information is dimmed for nodes and arcs not visible in the active window.
2. Click Done to dismiss the Information window.

An exact interface report is typically used on a subsystem node to provide detailed dependency information about the nodes within in it (in relation to nodes outside it).

To produce an exact interface report for the ListADT subsystem:

1. Select the ListADT subsystem node.
2. Choose Exact Interface from the Report menu.

   The report appears in a Text editor window; this editor is a separate process outside the direct control of rigiedit.

   

The report includes three kinds of information for the selected subsystem: provisions, requirements, and internalizations. A provision is a dependency from a node inside the subsystem to a node outside the subsystem; the internal node provides at least one object. A requirement is a dependency from a node outside the subsystem to a node inside the subsystem; the internal node requires at least one object. An internalization is a dependency between two nodes inside the subsystem.

To produce information about any particular arc:

1. Right-click on the arc.

   An Arc menu appears. You can bring up an Arc menu on any arc, even if it is not selected; the available choices apply to that arc.

2. Choose View Information from the Arc menu\ for the arc.

To produce an exact interface report for the composite arc between the ListADT and ElementADT subsystems:

1. Select the arc between the ListADT and ElementADT subsystem nodes.
2. Choose Exact Interface from the Report menu.

   A record of the lower-level dependencies between the two subsystems appears in a Text editor window. This editor is a separate process outside the direct control of rigiedit.

   

   Note: This report only works for composite arcs.
