Package org.kingdoms.utils.internal.nonnull

Class NonNullMap<K,V>

java.lang.Object

org.kingdoms.utils.internal.nonnull.NonNullMap<K,V>

All Implemented Interfaces:

Map<K,V>

public final class NonNullMap<K,V>
extends Object
implements Map<K,V>

No one uses maps to store null shit. Like what the fuck java. Note: put()'ing a null value with a valid key causes values() to return that null
