Method Detail

toIdentifiableSet

public static <T extends Identifiable> Collector<T,?,Set<T>> toIdentifiableSet()

Collect results into an identifiable set.

This uses Identifiable.getId() for comparing elements, making the collection safe for holding proxies unlike a HashSet that relies on Object.hashCode().

See Also:

Collectors.toSet()

toIdentifiableMap

public static <T,K extends Identifiable,U> Collector<T,?,Map<K,U>> toIdentifiableMap(Function<? super T,? extends K> keyMapper,
                                                                                                                   Function<? super T,? extends U> valueMapper)

Collect results into an identifiable map.

This uses Identifiable.getId() for comparing elements, making the collection safe for holding proxies unlike a HashMap that relies on Object.hashCode().

See Also:

Collectors.toMap(java.util.function.Function<? super T, ? extends K>, java.util.function.Function<? super T, ? extends U>)

toString

public static <T extends Identifiable> String toString(T identifiable,
                                                       Class<T> clazz)

Converts an identifiable to string, avoiding its initialization of it is a proxy.
