Method Details

getMappings

java.util.Iterator<GraphMapping<V,E>> getMappings()

Get an iterator over all calculated (isomorphic) mappings between two graphs.

Returns:

an iterator over all calculated (isomorphic) mappings between two graphs

Throws:

IsomorphismUndecidableException - if the inspector cannot decide whether the graphs are isomorphic

isomorphismExists

boolean isomorphismExists()

Check if an isomorphism exists.

Returns:

true if there is an isomorphism, false if there is no isomorphism

Throws:

IsomorphismUndecidableException - if the inspector cannot decide whether the graphs are isomorphic
