Interface Summary

Interface	Description
BasicEMap.Entry<K,V>	An extended implementation interface for caching hash values and for updating an entry that may be manufactured as a uninitialized instance by a factory.
Diagnostic	Information about the outcome of some activity.
DiagnosticChain	An accumulator of diagnostics.
EList<E>	A list that supports move.
EMap<K,V>	A list of java.util.Map.Entry instances, i.e., entries, that supports a EMap.map() view as well as the full Map API, with the notable exception of Map.remove(Object).
EMap.InternalMapView<K,V>	An internal interface implemented by the map view.
Enumerator	An interface implemented by the enumerators of a type-safe enum.
InterningSet<E>	A set that supports intern and get.
Logger	A logger of log entries.
Monitor	An task monitor that provides control and feedback.
Reflect.Helper	An interface implemented by reflective helpers.
