Class ObjectPair

java.lang.Object
org.apache.sis.metadata.ObjectPair
final class ObjectPair extends Object
A pair of objects in process of being compared by the MetadataStandard.equals(…) method. We have to remember those pairs for avoiding infinite recursivity when comparing metadata objects having cyclic associations. The objects are compared using the identity comparison. Object order is not significant.
