Discussion: Efficient ByteBuffer -> String that avoids additional copying

[Jacob Glickman]

Paul,

Would you mind explaining more about what you're looking for regarding
this?  I'm curious if `ByteBuffer#getString` is what you're after, or
rather something similar to `String.from(ByteBuffer)`.  I'll definitely
have a look at jdk.internal.misc.SharedSecrets in the meantime.  Thanks!

though i have not searched JBS), if you are willing to take it on. It will
require some investigation, and careful testing, it’s not necessarily a
starter bug :-), but i can help guide.

method on ByteBuffer that can avoid additional copying and makeappropriate
use of charsets given String’s compact string support. You need to look at
jdk.internal.misc.SharedSecrets for clues on how to trampoline between the
nio and lang packages.
