java - difference between bytebuffer.flip() and bytebuffer.rewind() -


i aware flip() set current buffer position 0 , set limit previous buffer position whereas rewind() set current buffer position 0.

in following code, either use rewind() or flip() same result.

byte b = 127; bb.put(b); bb.rewind();//or flip();  system.out.println(bb.get()); bb.rewind();// or flip(); system.out.println(bb.get());

could provide me real example difference of these 2 methods matters? in advance. edit: found solution in this link, it's explained , detailed thorough understanding of buffer , channel classes' use.

they're not equivalent @ all.

a bytebuffer ready read() (or put()).

flip() makes ready write() (or get()).

rewind() , compact() , clear() make ready read()/put() again after write() (or get()).

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
