java - Why field is injected into existing instance? -


i've found piece of code this

bind(my.class).to(new myprovider())  class myprovider implements provider<my> {     @inject injector injector = null;      get() {         return new my(injector.getinstance(another.class));     } } 

i've found guice injects injector later when injector being created though provider created new.

questions are:

  • is specified guice or accidental implementation detail?
  • is specified in jsr-330?
  • can rely on it?
  • how other di frameworks behave in such case?
  • if isn't specified anywhere, how 1 rewrite this? note i've omitted details, there several named bindings of same interface , each provider instance gets name parameter , gets named service injector.
