Package eu.bandm.tools.util.nonnull

Class MapProxy.NonNullMapEntrySet<A,B>

java.lang.Object

java.util.AbstractCollection<Map.Entry<A,B>>

java.util.AbstractSet<Map.Entry<A,B>>

eu.bandm.tools.util.nonnull.MapProxy.NonNullMapEntrySet<A,B>

Type Parameters:

A - the type of the keys

B - the type of the values

All Implemented Interfaces:

Iterable<Map.Entry<A,B>>, Collection<Map.Entry<A,B>>, Set<Map.Entry<A,B>>

Enclosing class:

MapProxy<K,V>

static class MapProxy.NonNullMapEntrySet<A,B>
extends AbstractSet<Map.Entry<A,B>>

Putting null as a value (not as a key) must also be prevented on this way: NonNullMap -> entrySet() -> NonNullMapEntrySet -> iterator() -> NonNullMapEntryIterator -> next() -> NonNullMapEntry
