Editing

The editing environment of the AGG system provides a comprehensive functionality for the input and modification of attributed graph grammars with a mouse/menu-driven user interface.

There are different editors:

• an editor for node and edge types with the possibility to name and set a simple graphical layout for each node and edge type,
• a graphical editor for graphs (host graphs and type graphs),
• a graphical editor for rules, that supports the editing of rules consisting of a left and a right hand rule side and (optionally) one or more negative application conditions (NACs),
• a textual editor for Java expressions which can be used as attributes,
• a tree view window to edit graph grammars and name its ingredients,
• a textual editor to order rules in layers.
