Class Hash

java.lang.Object
org.wikidata.wdtk.datamodel.helpers.Hash
public class Hash extends Object
Static class for computing a hashcode of arbitrary data objects using only their interfaces. This can be used to implement the hashCode() method of arbitrary interface implementations. More efficient solutions might exist if the object that implements an interface is of a specific known type, but the methods here could always be used as a fallback or default.
