Class EquiMap<K,V>

java.lang.Object
org.aksw.jena_sparql_api.views.EquiMap<K,V>
Type Parameters:
K -
V -
public class EquiMap<K,V> extends Object
A map where keys can be stated as equivalent. Provides methods for checking consistency (the map gets inconsistent as soon as a key maps to multiple non-equal values) TODO Not sure if a conflict resultion strategy for the case that values are not directly equal but not contradictory should go here. For instance if a key x maps to {A, B} and y maps to {A} one resolution stragtegy might be to map both to A. Essentially I have the ValueSets in mind to quickly reject inconsistent bindings.
