> Please review this PR and associated > [CSR](https://bugs.openjdk.org/browse/JDK-8327703) which introduces strict > parsing for NumberFormat. > > The concrete subclasses that will utilize this leniency value are > `DecimalFormat` and `CompactNumberFormat`. Strict leniency allows for parsing > to be used as an input validation technique for localized formatted numbers. > The default leniency mode will remain lenient, and can only be set to strict > through an intentional `setLenient(boolean)` method call. Leniency operates > differently based off the values returned by `isGroupingUsed()`, > `getGroupingSize()`, and `isParseIntegerOnly()`. > > Below is an example of the change, the CSR can be viewed for further detail. > > > DecimalFormat fmt = (DecimalFormat) NumberFormat.getNumberInstance(Locale.US); > fmt.parse("1,,,0,,,00,.23Zabced45"); // returns 1000.23 > fmt.setLenient(false); > fmt.parse("1,,,0,,,00,.23Zabced45"); // Now throws a ParseException > fmt.setGroupingSize(2); > fmt.parse("12,34,567"); // throws ParseException > fmt.setParseIntegerOnly(true) > fmt.parse("12,34.56"); // throws ParseException > fmt.parse("12,34"); // successfully returns the Number 1234 > > > The associated tests are all localized, and the data is converted properly > during runtime.
Justin Lu has updated the pull request incrementally with one additional commit since the last revision: Replace protected field with a public getter -> isStrict(). Replace setLenient() with setStrict() to avoid messy inversion of boolean. Add a leniency section to NumberFormat. Overhaul of NumberFormat class specification to be much more organized/readable. ------------- Changes: - all: https://git.openjdk.org/jdk/pull/18339/files - new: https://git.openjdk.org/jdk/pull/18339/files/8843c56f..c3a32500 Webrevs: - full: https://webrevs.openjdk.org/?repo=jdk&pr=18339&range=01 - incr: https://webrevs.openjdk.org/?repo=jdk&pr=18339&range=00-01 Stats: 208 lines in 5 files changed: 77 ins; 54 del; 77 mod Patch: https://git.openjdk.org/jdk/pull/18339.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/18339/head:pull/18339 PR: https://git.openjdk.org/jdk/pull/18339
