java - btrace visualvm interfaces require ASM 5 -


when run simple java8 program

package test;  public class traceint { public static void main(string args[]) throws interruptedexception{     traceint ti = new traceint();     while(true){         integer.valueof((int)system.currenttimemillis());         ti.sleep(1000);         //system.getproperty("user.dir");     } }  public void sleep(int millis){     try {         thread.sleep(millis);     } catch (interruptedexception e) {         // todo auto-generated catch block         e.printstacktrace();     } } }

and run btrace script against it

@onmethod(     clazz = "/.*/",     method = "/java.lang.*/",     location = @location(value = kind.entry, = where.before) ) public static void onentry(object obj) {     println(strings.strcat("on entry: ", identitystr(obj))); }

i error in program

any appreciated

after while realised using old version of btrace against java8. moved latest version fine.

angular - Is it possible to get native element for formControl? -

i've got angular2 reactive form . created formcontrol s , assigned input fields by [formcontrol]=... . understand creates nativeelement <-> formcontrol link. my question: possible nativeelement formcontrol ? wanna myformcontrol.nativeelement.focus() i can share 1 terrible solution works me. in reactive forms can use either 1) formcontroldirective ts mycontrol = new formcontrol('') template <input type="text" [formcontrol]="mycontrol"> or 2) formcontrolname ts myform: formgroup; constructor(private fb: formbuilder) {} ngoninit() { this.myform = this.fb.group({ foo: '' }); } template <form [formgroup]="myform"> <input type="text" formcontrolname="foo"> </form> so these directives write patch like 1) formcontroldirective const originformcontrolngonchanges = formcontroldirective.prototype.ngonchanges; formcontroldirective.proto

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this
