Hi Mark, hi Stuart, hi all,
for Map, i think a version with a builder will be cool too,
something like:
public interface EntryBuilder<K, V> {
public EntryBuilder<K,V> entry(K key, V value);
}
and by example for HashMap:
public static <K, V> HashMap<K, V> fromBuilder(Consumer<? super
EntryBuilder<K,V>> consumer) {
HashMap<K,V> map = new HashMap<>();
consumer.accept(new EntryBuilder<>() {
public EntryBuilder<K,V> entry(K key, V value) {
map.put(key, value);
return this;
}
});
return map;
}
...
HashMap<String, Integer> map = HashMap.fromBuilder(b -> b
.entry("foo", 1)
.entry("bar", 2));
The builder pattern let us to avoid to create intermediary entry objects.
regards,
Rémi
