Release notes

This is the first stable version available for production. It is highly recommended to upgrade to this version if you have used a previous version.

Bugs

  • Fix unsigned compare bugs.
  • Fix Lookup.ApplyResultSelector bugs.
  • Fix OrderedEnumerableRangeEnumerator not iterate maxIdx.
  • Fix EnumerablePartition error assert.
  • Fix inner enumerator of CrossJoinIterator and SelectManyIterator dispose twice.
  • Fix not check selector param for sum with selector.
  • Fix bug with select(...).count() on an IPartition.
  • Fix bug with skip, take on an empty IOrderedEnumerable.
  • Fix union and unionBy not close when break iterate.

Features

  • Add zip Tuple api.
  • Add support compatible stream for IEnumerable.
  • Add api toLinkedList, toLinkedMap, toLinkedSet, toCollection for IEnumerable.
  • Add api indexOf, lastIndexOf for IEnumerable.
  • Add api findIndex, findLastIndex for IEnumerable.
  • Add api format, joining for IEnumerable to print values.
  • Add api ofNullable, chars, words, lines, split, infinite, loop, enumerate, iterate for Linq.
  • Add _indexOf and _lastIndexOf method for IList.
  • Add _findIndex() and _findLastIndex() method for IList.
  • Add IArrayList interface which extends RandomAccess for random access list and IList for other.
  • Add IArray interface to determine IArrayList contains an array or not.
  • Add CultureInfo.setCurrent to set current locale for string actions in linq.
  • Add StringComparer for string equals, hashCode and compare actions.
  • Add ValueType as super class for value type.
  • Add support more type cast to IEnumerable like IEnumerable, Iterator and Enumeration.
  • Add Linq.as() to generate IEnumerable from Object.
  • Add debug view support.
  • Add primitive functional interface.
  • Add covariant & contravariant support.

Optimizations

  • Remove override runOnce() for IList.
  • Not copy data when cast primitive array to IEnumerable.
  • Not create array when cast singleton to IEnumerable.
  • Optimize performance of takeLast.
  • Optimize range().select() and repeat().select().
  • Optimize min, max, minBy, maxBy performance.
  • Optimize TakeLastIterator dispose action.
  • Optimize toMap and toSet methods.
  • Optimize indexOf and lastIndexOf in EqualityComparer.
  • Optimize skipLast performance.
  • Optimize performance by use enumerator instead of iterator.
  • Implements IIListProvider for DistinctByIterator, CrossJoinIterator, UnionByIterator.

Changes

  • Translated all LINQ to Objects API of .net core 3.0.
  • Use ThrowHelper to throw Exceptions.
  • Rename package bridge to adapter.
  • Rename Linq.asEnumerable() to Linq.of().
  • Rename TupleMore to TupleN.
  • Rename Linq.of(CharSequence) to Linq.chars(CharSequence).
  • Update junit version to 5.x.
  • Update plugin version to latest.
  • Change the year of copyright.

Parameters covariant
