java.lang.Object
- software.amazon.awssdk.utils.ImmutableMap<K,V>

Type Parameters:: K - Class of the key for the map.; V - Class of the value for the map.

All Implemented Interfaces:: Map<K,V>

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

An immutable map that could be built by convenient constructors.

Example of using map Builder:

 {
     @code
     Map<String, AttibuteValue> item = new ImmutableMap.Builder<String, AttibuteValue>()
             .put("one", new AttibuteValue("1"))
             .put("two", new AttibuteValue("2"))
             .put("three", new AttibuteValue("3")).build();
 }

For small immutable maps (up to five entries), the ImmutableMapParamter.of() methods are preferred:

 
   Map<String, AttibuteValue> item =
       ImmutableMap
           .of("one", new AttributeValue("1"),
               "two", new AttributeValue("2"),
               "three", new AttributeValue("3"),
