java - Reading from response body multiple times in Apache HttpClient 4.x -

-

i'm using apache httpclient 4.2.3 in application. store response of http call so:

httpresponse httpresponse = (defaulthttpclient)httpclient.execute(httprequest);

the response body inputstream in 4.x api:

inputstream responsestream = httpresponse.getentity().getcontent();

my problem need read response body string , byte[] @ various points in application. inputstream used apache eofsensorinputstream, means once reach stream eof, gets closed. there anyway can string , byte[] representations multiple times , not close stream?

i've tried wrapping byte array in new bytearrayinputstream , setting request body, doesn't work since response body can reach few gigs. i've tried this, noticed original response stream still gets closed.

any pointers welcome.

edit: on related note, great if find length of inputstream either without consuming stream or reversing consumption.

1 . think have conflicting requirements:

a)

it doesn't work since response body can reach few gigs

b)

is there anyway can string , byte[] representations multiple times , not close stream

if not have enough memory not possible.

btw, way response bytes entityutils.byte[] tobytearray(final httpentity entity).

do need n-gigs string? going it?

2 .

it great if find length of inputstream

httpresponse.getentity().getcontentlength()

3 . since response not fit memory suggest save file (or temp file). set inputstream on file, , read many times need.

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2...

i need place custom knob image shadow uislider. far have image of 38x38, of there region defines shadow of knob. now while using image, when slide knob extreme ends actual knob not able cover end points, hence end points visible under transparent region of knob image this code using customize uislider uiimage *slidebtimg = [uiimage imagenamed:sliderknobimg]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatenormal]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatehighlighted]; how can implement custom knob shadow beneath it, covering end points?? look inside uislider.h , there methods let customize slider knob , track needed.
