Class Equality

java.lang.Object

org.wikidata.wdtk.datamodel.helpers.Equality

public class Equality
extends Object

Static class for checking the equality of arbitrary data objects using only their interfaces. This can be used to implement the equals() 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.

Note that it is desired that different implementations of the same interface are treated as equal if they contain the same data.
