java - Why the emphasis on typed attributes/methods in MBean definition? -

-

from oracle's definition of mbeans:

mbeans managed beans, java objects represent resources managed. mbean has management interface consisting of:

  1. named , typed attributes can read , written.
  2. named , typed operations can invoked
  3. typed notifications can be> emitted mbean

why emphasis on typed in each of points above? java typed language , attributes/methods in java class have type attached them. finding definition confusing. or missing fundamental here? using typed mean different?

jmx has more restrictive typing characteristics because often, types providing form of "identity" or signature bean attribute or operation. in addition, jmx supports notion of open types complex type broken down primitive definitions can represented externally jvm (perhaps in jconsole specific class might not in classpath.)

don't hung on though... means mbean's attributes defined name, , type. no surprise there :)

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...

Image
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.
