```
public class SubGraphConstructor
extends Object
```
Supports the construction of subgraphs of a ModelGraph. To that end, it maintains a ModelGraphMapping from the subgraph to the original graph and offers methods to extend the subgraph.

  - addNodeCopy
```
public ModelNode addNodeCopy(ModelNode node)
                      throws GraphManipulationException
```
    Adds a copy of a node of the complete graph to the subgraph if the node is not already represented there.
    
    Parameters:
    
    node - a node of the underlying complete graph
    
    Returns:
    
    the node representing the given node in the subgraph
    
    Throws:
    
    GraphManipulationException - if adding the node was aborted - in this case the subgraph remains unchanged
  - addEdgeCopy
```
public ModelEdge addEdgeCopy(ModelEdge edge)
                      throws GraphManipulationException
```
    Adds a copy of an edge of the complete graph to the subgraph if the edge is not already represented there. Also creates and adds copies of source and target nodes if necessary.
    
    Parameters:
    
    edge - an edge of the underlying complete graph
    
    Returns:
    
    the edge representing the given edge in the subgraph
    
    Throws:
    
    GraphManipulationException - if adding the edge was aborted - in this case the subgraph remains unchanged
