Method Detail

append

default Fluent.Map<K,V> append(K key,
                               V val)

Returns:

self-reference

See Also:

java.util.Map#put(K, V)

appendAll

default Fluent.Map<K,V> appendAll(Map<? extends K,? extends V> map)

Returns:

self-reference

See Also:

Map.putAll(java.util.Map)

append

default Fluent.Map<K,V> append(Map.Entry<? extends K,? extends V> entry)

Equivalent to append(key, value) of the input entry

Parameters:

entry - map entry

Returns:

self-reference

See Also:

#append(K, V)

unmodifiable

default Map<K,V> unmodifiable()

Returns an unmodifiable view of this map. Best used at the end of fluent construction thereby providing an effectively immutable map (as the backing mutable map is unreachable). For example:

   Map<String, Integer> immutable = new Fluent.HashMap<String, Integer>()
       .append("one", 1)
       .append("two", 2)
       .append("three", 3)
       .unmodifiable();
 

See java.util.Collections#unmodifiableMap(Map)

Returns:

an unmodifiable view of this map
