java - How to inject a implementation that takes some value in its constructor in Guice? -


i have following implementation trying inject in guice

`public class client{     private final database db;     public client(database db){       this.db = db     }  }  class someclass{    private client client;     @inject    public someclass(client client){      this.client = client;    }  }`

this injection code injector guice = guice.injector(); guice.getinstance(someclass.class);

but keep on getting error:

could not find suitable constructor in hello.package.helloworld.client. classes must have either 1 (and one) constructor annotated @inject or zero-argument constructor not private

how inject class takes parameter?

the error text quite explicit: haven't used @inject on constructor of client.

so idea make so:

public class client{    private final database db;    @inject   public client(database db){      this.db = db    }  }

and if don't know database, want create it, consider using guice's assisted injection, creates factory you.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
