mapEntries() works like map and mapKeys, but accepts and returns [key, value] tuples, enabling mapping both keys and values simultaniously.
toKeyedSeq() converts an IndexedSequence into a Sequence where the indices are treated as keys. This is a lazy operation.
The whole IndexedSequence API has been reworked to remove the third maintainIndices argument from many methods. Using maintainIndices resulted in a sparse IndexedSequence, which no longer made sense in the context of dense IndexedSequences.
Example:
// Old: [0,,2,,4,,6,,8,,]
Range(0,10).filter(isEven, null, true)
// New: { 0: 0, 2: 2, 4: 4, 6: 6, 8: 8 }
Range(0,10).toKeyedSeq().filter(isEven)
If you were using this argument, you will need to use toKeyedSeq() first to achieve similar behavior. This change warrants the minor-version bump.
Bugs:
- Returning false from forEach() often resulted in an incorrect length iterated. Clarified the documentation describing this behavior and corrected any bad behavior.
- Fixed some documentation which referenced sparse behavior.
- Fixed some issues when using reverse() and take() or skip() in concert that resulted in incorrect indices.
- Fixed incorrect behavior when take() or skip() are given negative values.
- Fixed issue where iteration of valueSeq() didn't provide the correct collection as a third argument.
- Fixed issue where flatten() and concat() behavior diverged.
