Class Tries

java.lang.Object

dmx.fun.Tries

@NullMarked
public final class Tries
extends Object

Collector facade for Stream<Try<V>>.

Centralises all Try collector factories as static methods, mirroring the role of Collectors. The underlying factories on Try are kept for backward compatibility; this class simply delegates to them.

Usage:

import static dmx.fun.Tries.*;

Try<List<String>>       result = stream.collect(Tries.toList());
Tries.Partition<String> p      = stream.collect(Tries.partitioning());
p.successes(); // List<String>
p.failures();  // List<Throwable>

Modifier and Type	Method	Description
static <V> Collector<Try<V>, ?, Tries.Partition<V>>	partitioning()	Returns a Collector that partitions a Stream<Try<V>> into successes and failures.
static <V> Collector<Try<V>, ?, Try<List<V>>>	toList()	Returns a Collector that accumulates a Stream<Try<V>> into a single Try<List<V>>, failing on the first Failure encountered.

Method Details

toList

public static <V>
Collector<Try<V>, ?, Try<List<V>>> toList()

Delegates to Try.toList().

Type Parameters:

V - the success value type

Returns:

a collector producing Try<List<V>>

partitioning

public static <V>
Collector<Try<V>, ?, Tries.Partition<V>> partitioning()

Returns a Collector that partitions a Stream<Try<V>> into successes and failures.

Delegates to Try.partitioningBy().

Type Parameters:

V - the success value type

Returns:

a collector producing a Tries.Partition
