Planning page for JDT Implementation of Switch Expressions (JEP 325) for Java 11
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
Compiler AST Creation
Tied with parsing - dkne
Flow analysis changes
will have flow analysis changes - in progress - 3 days.
Type checking
Type inference will have to be dom since switch may be an expression - <=5 days?
Error reports
- new error reports. (2 days - in parallel with flow analysis ?) - in progress in parallel
Code generation
Addressing the breaks without label but with expressions and implicit break labels for switch label expressions - 5 days
Java Search support
slight change expected - 2d bug 542559
DOM support
ast changes expected - 1wk - can give an estimate after the compiler ast structure is done - initial discussion done bug 542558
Content Assist support
- additional place the content assist be applicable - 5 days (bug 542560
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
Code templates
- add switch in templates - 1d
JDT Debug
- Expected to have an impact - especially breakpoints - 1w approx
