- widen API from LocalePriorityList to Iterable
- merge getBestMatch(multiple locales) and getBestMatch(single locale) into one function
- process desired locales incrementally, create fewer objects
- reject poor matches early: use bestDistance-demotion for threshold
- add API for java.util.Locale, convert incrementally
- new feature: tracks indexes of supported and desired locales which eliminates conversion of result objects in wrappers around getBestMatch() as shown by the java.util.Locale API here
- simpler data structures, more serialization-friendly (easier to port to C++)
- e.g., use a BytesTrie each for likelySubtags & locale distance, instead of layers of TreeMap
- un-hardcode locale matcher data; use modern resource bundle functions
- split builder code & runtime code into separate classes
- move LSR to simple top-level value class, cache regionIndex in LSR
- simpler handling of private use languages and pseudolocales
- simplify RegionMapper
- LocaleDistance builder: move the node distance into the DistanceTable, remove DistanceNode
- support distance rules with region codes, not just with variables
- enforce & use distance rule constraints:
- no rule with *,supported or desired,*
- no rule with language * and script/region non-*
- distance trie collapse a (desired, supported)=(ANY, ANY) pair into a single *
- look up each desired language only once for all supported LSRs
- remove layers-of-Maps compaction (trie builder compacts)
- remove unused XML printing
- remove other unused code
- make XLocaleMatcherTest.testPerf() exercise locale distance lookup code
- Wires up FormattedNumber[Range] in applicable languages.
- Adds new header files and tests, with minor cleanup to old tests.
- Adds code to guarantee terminating NUL in FormattedNumber[Range].
- Cleanup of API docs for inherited methods in FormattedNumber[Range].
Adds some plumbing to allow MutablePatternModifier to set fields, and otherwise builds upon the infrastructure from the previous commit to add the MEASURE_UNIT field.
- fastpath for UnicodeSet.add(new last range)
- fewer UnicodeSet memory allocations:
initial internal list array, exponential array growth,
allocate strings list/set only when first one is added
- faster CodePointTrie.getRange(): fewer calls to filter function
- revert UnicodeSet(intprop=value) from trie ranges to range starts + lookup
- cache per-int-prop range starts: fewer lookups
