Hello! Great work, thanks! Seems that the new document steps away from dedicated matching operator like __matches which we saw before and reuses instanceof instead. Does this mean that sole type name like String which is used in instanceof currently is also a pattern? This could conflict with named constant. E. g.:
class Test { static final int String = 5; void test(Object obj) { if(obj instanceof String) { // obj == 5 or is a string? } } } With best regards, Tagir Valeev. сб, 8 сент. 2018 г., 1:41 Brian Goetz <brian.go...@oracle.com>: > I've updated the documents regarding pattern matching, and uploaded them > here: > > http://cr.openjdk.java.net/~briangoetz/amber/pattern-match.html > http://cr.openjdk.java.net/~briangoetz/amber/pattern-semantics.html > > The first document is an update of a previous document (old version > available here: > http://cr.openjdk.java.net/~briangoetz/amber/pattern-match_1.html), and > outlines the general arc of the feature and general motivation. > > The second captures the discussions we've had regarding the messy > details of typing, scoping, nullability, shadowing, etc. I think we've > made a lot of progress on these. > > We would not implement this all at once; we'd proceed incrementally, > probably starting with type patterns in `instanceof`, and then > proceeding to `switch` or to deconstruction patterns. > > Please review and comment. > >
