Assets 6
  • Added ofNullable for primitive Optionals (thanks to @mannodermaus)

Assets 6
  • Added Optional.mapToBoolean (thanks to @bejibx)
  • Added Stream.equalsOnly operator (thanks to @operando)
  • Added deepEquals, requireNonNullElse, requireNonNullElseGet, isNull, nonNull and requireNonNullElements methods to Objects (thanks @ened for suggestion)
  • Added orElseThrow() method to Optional classes. Please, prefer this method instead of get() as it better reflects the behavior of the method
  • Added toUnmodifiableList(), toUnmodifiableSet() and toUnmodifiableMap() collectors from Java 10 (thanks to @javadev and @PromanSEW). See PromanSEW's comment
  • The Collectors.toMap implementation was changed to match Java 8 specs. toMap(keyMapper), toMap(keyMapper, valueMapper) and toMap(keyMapper, valueMapper, mapFactory) now disallows duplicate keys. If the mapped keys contain duplicates, use new toMap(keyMapper, valueMapper, mergeFunction) and toMap(keyMapper, valueMapper, mergeFunction, mapFactory) methods
  • Removed useless FunctionalInterface annotation
  • Removed deprecated Stream.getIterator method

Assets 6
  • Added primitive throwable interfaces and Util.safe converters. Thanks to @PromanSEW
  • Improved comparators chaining in ComparatorCompat . Thanks to @BattleShipPark
  • Fixed filter operator in primitive streams. Thanks to @RomainPiel

Warning

If you're using PrimitiveIterator, PrimitiveExtIterator or LsaExtIterator to create own custom operators, please, fix imports:

// Before
import com.annimon.stream.PrimitiveIterator;
import com.annimon.stream.LsaExtIterator;

// After
import com.annimon.stream.iterator.PrimitiveIterator;
import com.annimon.stream.iterator.LsaExtIterator;

If you're using ComparatorCompat.chain, see #110

Assets 6
  • Added Stream.withoutNulls() Stream.nullsOnly() and Predicate.Util.notNull(). Thanks to @IlyaGulya
  • Added Java 8 Comparator backport. Thanks to @BattleShipPark
