 | INamed |
An named IGraph (which is an attributed, typed and directed multigraph with multiple inheritance on node and edge types),
with a unique name assigned to each node and edge; allowing to access an element by name and a name by element.
Namespace: de.unika.ipd.grGen.libGr

SyntaxC#
public interface INamedGraph : IGraph
The INamedGraph type exposes the following members.
Properties| Name | Description | |
|---|---|---|
 | ChangesCounter |
Returns a counter of the number of changes that occured since the graph was created.
If it's different since last time you visited, the graph has changed (but it may be back again in the original state).
Only graph structure changes are counted, attribute changes are not included.
(Inherited from IGraph) |
| CustomCommandsAndDescriptions |
The graph-backend dependent commands that are available, and a description of each command.
(Inherited from IGraph) |
| Edges |
Enumerates all edges in the graph.
(Inherited from IGraph) |
| GlobalVariables |
The global variables of the graph rewrite system; convenience access to save parameter passing.
(Inherited from IGraph) |
| GraphId |
A unique id associated with the graph
(Inherited from IGraph) |
| Indices |
The indices associated with the graph.
(Inherited from IGraph) |
| Model |
The model associated with the graph.
(Inherited from IGraph) |
| Name |
A name associated with the graph.
(Inherited from IGraph) |
| Nodes |
Enumerates all nodes in the graph.
(Inherited from IGraph) |
| NumEdges |
The total number of edges in the graph.
(Inherited from IGraph) |
| NumNodes |

(Inherited from IGraph) |
| ReuseOptimization |
If true (the default case), elements deleted during a rewrite
may be reused in the same rewrite.
As a result new elements may not be discriminable anymore from
already deleted elements using object equality, hash maps, etc.
In cases where this is needed this optimization should be disabled.
(Inherited from IGraph) |
| UniquenessHandler |
The uniqueness handler associated with the graph.
(Inherited from IGraph) |

| ChangedEdgeAttribute |

For debugging, won't be automatically called in case of -nodebugevents, attribute change rollback is based on the pre-events.
(Inherited from IGraph) |
| ChangedNodeAttribute |
Fires an OnChangedNodeAttribute event.
For debugging, won't be automatically called in case of -nodebugevents, attribute change rollback is based on the pre-events.
(Inherited from IGraph) |
| ChangingEdgeAttribute |
Fires an OnChangingEdgeAttribute event.
To be called before changing an attribute of an edge,
with exact information about the change to occur,
to allow rollback of changes, in case a transaction is underway.
(Inherited from IGraph) |
| ChangingNodeAttribute |
Fires an OnChangingNodeAttribute event.
To be called before changing an attribute of a node,
with exact information about the change to occur,
to allow rollback of changes, in case a transaction is underway.
(Inherited from IGraph) |
| ChangingObjectAttribute |

with exact information about the change to occur,
to allow rollback of changes, in case a transaction is underway.
(Inherited from IGraph) |
| Check |
Checks whether the internal data structures are ok (will throw an exception if they are not).
This is for debugging the underlying implementation from positions outside the implementation.
(Inherited from IGraph) |
| Clear |
Removes all nodes and edges from the graph (so any variables pointing to them start dangling).
Also resets the class object unique id source.
(Inherited from IGraph) |
| Clone(String) |

The new graph will use the same model as the other.
(Inherited from IGraph) |
| Clone(String, IDictionaryIGraphElement, IGraphElement) |

This is a safe but O(n) operation, as it resets the visited flag in the graph.
(Inherited from IGraph) |
| FreeVisitedFlagNonReset |
Frees a clean visited flag.
This is an O(1) but potentially unsafe operation.
Attention! A marked element stays marked, so a later allocation hands out a dirty visited flag!
