= Planning page for JDT Implementation of Switch Expressions (JEP 325) for Java 11 =

Main tracking bug: {{bug|531714}}

== Compiler changes ==
Changes regarding the compiler: 
=== 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 - expected to be done 3-5 days the basic structure - 2d remaining
=== Flow analysis changes ===
will have flow analysis  changes  - started in parallel - 3 days.

=== Type checking ===
Type inference will have to be dom since switch may be an expression - <=7 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

== DOM support ==
ast changes expected - 1wk - can give an estimate after the compiler ast structure is done

== Content Assist support ==
* additional place the content assist be applicable - 2 days (opportunistic)

== 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 since coase statements - 4 ays> jdt.ui ? opportunistic

=== Code templates ===
* add switch in templates - 1d

=== JDT Debug ===
* Expected to have an impact - especially breakpoints - 1w approx
