public interface EMap<K,V>
A list of java.util.Map.Entry
instances, i.e., entries, that
supports a map()
view
as well as the full Map
API,
with the notable exception of Map.remove(Object)
.
It's return type conflicts with that of Collection.remove(Object)
.
The removeKey(Object)
method may be used instead.
The implementation of remove may delegate to removeKey
for an object that is not an instance of Map.Entry
.
