Hello!
Here's the proposal by Martin Buchholz to improve implementation of
StringJoiner class:
http://cr.openjdk.java.net/~martin/webrevs/openjdk9/StringJoiner-optimization/
I think that result of concatenation in the merge() method can be saved
to be reused later.
This would be useful, for example, if a StringJoiner is merged into
other StringJoiners several times.
So, here's my slightly modified version of the Martin's webrev:
http://cr.openjdk.java.net/~igerasim/8054221/0/webrev/
I've also modified the test to regularly test cases with empty
prefixes/suffixes.
Sincerely yours,
Ivan
