java - write to socketchannel from one thread and select from other thread -


can write socketchannel 1 thread, while same socketchannel may being selected selector#select() io operations in other thread? thread-safe? or have delegate bytebuffers other thread (which selector#select() indefinitely), written socketchannel every after selector#select() calls.

also, selectionkey#interestops(int) set interest operations thread-safe? or have delegate same other thread (which selector#select() indefinitely).

yes can,in general. thread that's blocked in select() isn't using bytebuffer while it's blocked. if elsewhere, of course need synchronize, or take other measure.
