Class ImmutableMapWithNullValues<K,V>

java.lang.Object

graphql.collect.ImmutableMapWithNullValues<K,V>

Type Parameters:

K - for key

V - for victory

All Implemented Interfaces:

Map<K,V>

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

The standard ImmutableMap does not allow null values. The implementation does. We have cases in graphql, around arguments where a map entry can be explicitly set to null and we want immutable smart maps for these cases.
