VF2GraphMappingIterator

java.lang.Object
- org.jgrapht.alg.isomorphism.VF2MappingIterator<V,E>
- - org.jgrapht.alg.isomorphism.VF2GraphMappingIterator<V,E>

Type Parameters:

V - the type of the vertices

E - the type of the edges

All Implemented Interfaces:

java.util.Iterator<GraphMapping<V,E>>
```
class VF2GraphMappingIterator<V,E>
extends VF2MappingIterator<V,E>
```
This class is used to iterate over all existing (isomorphic) mappings between two graphs. It is used by the VF2GraphIsomorphismInspector.

    Description copied from class: VF2MappingIterator
    
    This function moves over all mappings between graph1 and graph2. It changes the state of the whole iterator.
    
    Specified by:
    
    match in class VF2MappingIterator<V,E>
    
    Returns:
    
    null or one matching between graph1 and graph2
