JDT Core/Plan/4.8/JEP325
Contents
Planning page for JDT Implementation of Switch Expressions (JEP 325) for Java 12
Main tracking bug: bug 542557
Compiler changes
Changes regarding the compiler: bug 542557
Grammar changes
Switch Expression grammar changes - add bug number This would be a major grammar change effort/time estimate for grammar - Currently here - need to rewrite the grammar - est : done Additional minor but required grammar change was done to include parenthesis.
Compiler AST Creation
Tied with parsing - done
Type Inference
Type inference since switch expression may be an expression - bug 542871 - Done
Flow analysis changes
will have flow analysis changes - bug 542707 - done
Error reports
- new error reports. (0 days - in parallel with flow analysis) - done
Code generation
Addressing the breaks without label but with expressions and implicit break labels for switch label expressions -0d bug 542838 - done Further issues found bug 544458 - 1d
Java Search support
slight change expected - 0d bug 542559 - done Additional issue found in bug 544304 - done
DOM support
ast changes expected - 1wk -- DOM AST changes are released, more tests to be added.
bug 542558
ast rewrite - 3 days - work in progress
bug 543720
Content Assist support
- additional place the content assist be applicable - 5 days (bug 542560 - in progress
Code Select support
- additional place the content assist be applicable - 5 days (bug 542561
UI Changes
- Switch ASTs to JLS11 (generic - 1d)
Code hover
- Show inferred type of variable - no change expected
Preferences
- Allow JDT UI to target Java 11 in Compiler Preferences - generic (1d in parallel)
Quick fixes
- convert to a switch statement ( 3 DAYS? jdt.ui to comment)
- coalesce two or more case statements to comma separated case label statements - 4 ays> jdt.ui ? opportunistic
- see bug 543665
Code templates
- add switch in templates - 1d
JDT Debug
- Expected to have an impact - especially breakpoints - 1w approx
