debugging - Java: how to get arguments passed to method that called this method? -

-

in java, possible class , method called current method (the method in stacktrace).

my question is, can arguments passed method called method?

i need debugging purposes.

eg:

baseclass {    initialfunc(input) {        var modifiedinput = input + " modified you";        otherclass.dosomething(modifiedinput);    } }  otherclass {     dosomething(input)  {          //get arguments passed method of class called method     } }

can 1 information stacktrace, or there other means?

(note need able in runtime , cannot change source of baseclass, going feature of debugging class not know source beforehand)

thanks.

i don't believe possible using standard java api.

what use aspectj, place point-cut @ calling method, save arguments, place point-cut @ called method , pass on arguments.

another option (slightly more advanced) use custom, bytecode-rewriting, class loader saves original arguments, , passes them on arguments next method. take day or 2 implement. suitable frameworks bcel or asm.

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,...

binding - How can you make the color of elements of a WPF DrawingImage dynamic? -

-
we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing....
