Class MapBuilder<K,V,M extends Map<K,V>>

java.lang.Object

com.kingsrook.qqq.backend.core.utils.collections.MapBuilder<K,V,M>

public class MapBuilder<K,V,M extends Map<K,V>>
extends Object

Map.of is "great", but annoying because it makes unmodifiable maps, and it NPE's on nulls... So, replace it with this, which returns HashMaps (or maps of the type you choose). Can use it 2 ways: MapBuilder.of(key, value, key2, value2, ...) => Map (a HashMap) MapBuilder.of(() -> new SomeMapinvalid input: '<'SomeKeyType, SomeValueType>()).with(key, value).with(key2, value2)...build() => SomeMap (the type you specify)
