Anhang C. Glossary

Operation which moves all selected RFG-Objects (including all RFG-Objects located in the hierarchically structure below the selected RFG-Objects) into the current User View.

Interaction between user and OpenCAGE. It is specified by a Use-Case.

A value configurable by the user, which is used to decide whether two nodes are identical or not.

Function that tries to detect architectural information in the RFG. The gathered data will be stored in a new view.

Optional text which describes an element of OpenCAGE (e.g. nodes, edges, ...)

Logical integral part of the handled RFG. Main goal of the work with OpenCAGE is to divide the whole RFG into non-overlapping architecture components.

Special type of Composite Node. It is used to give the analyzed program a proper structure. It builds up the hierarchical levels between the nodes.

Nodes and edges have a wide variety of attributes. Different node and edge types have different numbers and types of attributes.

If a conflict/error occurs during an RFG manipulation operation (eg. Accept) all RFG-Objects that are involved in this error are highlighted, i.e. they are visualized as pixmaps specified by the user. The user has to remove the conflict highlighting of the affected nodes.

[GUI] Pointer that is shown while the metric window mode is active

Specifies the actions/operations which can be performed in the Graph Area.

The Mode Master is used to run operations selected by the user on a Graph Area. They are displayed in a dialog.

Mode that can be switched to by using the buttons in the toolbar. There are standard mode and zoom mode.

Mode that can be switched to by using a Mode Master. The chosen mode is active until the user clicks an OpenCAGE-Window. Temporary modes always replace the current active mode.

[GUI] Pointer that is shown while a move operation is performed.

Multiple relation between two nodes.

Neighbor Nodes are nodes that are connected by an edge.

[GUI] Pointer that indicates that the current permanent mode is not valid in this place.

User adjustment for analysis, filter or layout.

[GUI] Pointer that is shown while a paste operation is executed.

Graphical element (eg. picture) used to display a special type of RFG-Object.
