Class AMap<K,V>

java.lang.Object

java.util.AbstractMap<K,V>

java.util.HashMap<K,V>

java.util.LinkedHashMap<K,V>

org.apache.juneau.utils.AMap<K,V>

Type Parameters:

K - The key type.

V - The value type.

All Implemented Interfaces:

Serializable, Cloneable, Map<K,V>

public final class AMap<K,V>
extends LinkedHashMap<K,V>

An extension of LinkedHashMap with a convenience append(Object,Object) method.

Primarily used for testing purposes for quickly creating populated maps.

// Example: Map<String,Integer> m = new AMap<String,Integer>() .append("foo",1).append("bar",2);
