android - Dagger 2 : Presenter is null -


need assistance in understanding why splash presenter returned null. following clean architecture.

public class splashactivity extends baseactivity implements hascomponent<logincomponent> {      @inject     splashpresenter splashpresenter;      private logincomponent logincomponent;       @override protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         requestwindowfeature(window.feature_indeterminate_progress);         //setcontentview(r.layout.spla);          this.initializeinjector();         if (savedinstancestate == null) {            // addfragment(r.id.fragmentcontainer, new userlistfragment());         }          splashpresenter.initialize();     }      private void initializeinjector() {         this.logincomponent = daggerlogincomponent.builder()                 .applicationcomponent(getapplicationcomponent())                 .activitymodule(getactivitymodule())                 .loginmodule(new loginmodule())                 .build();     }      @override     public logincomponent getcomponent() {         return logincomponent;     } }

in activity splashpresenter null.

here activity component

@peractivity @component(dependencies = applicationcomponent.class, modules = activitymodule.class) public interface activitycomponent {   //exposed sub-graphs.   activity activity(); }  @module public class activitymodule {   private final activity activity;    public activitymodule(activity activity) {     this.activity = activity;   }    /**   * expose activity dependents in graph.   */   @provides @peractivity activity activity() {     return this.activity;   } }

here logincomponent

 @peractivity     @component(dependencies = applicationcomponent.class, modules = {activitymodule.class, loginmodule.class})     public interface logincomponent extends activitycomponent {   }

here loginmodule

@module public class loginmodule {      private user user;      public loginmodule(){}      public loginmodule(user user){this.user = user;}      @provides   loginrepository provideloginrepository(logindatarepository loginrepository) {     return loginrepository;   }       @provides     @peractivity     @named("isuserloggedin")     usecase provideisuserloggedinusecase(isuserloggedin isuserloggedin){         return isuserloggedin;     }      @provides     @peractivity     @named("login")     usecase provideloginusecase(loginrepository loginrepository, threadexecutor threadexecutor, postexecutionthread postexecutionthread){         return new login(user,loginrepository,threadexecutor,postexecutionthread);     }      @provides     @peractivity     @named("logout")     usecase providelogoutusecase(loginrepository loginrepository, threadexecutor threadexecutor, postexecutionthread postexecutionthread){         return new logout(user,loginrepository,threadexecutor,postexecutionthread);     } }

in baseactivity doing following

public abstract class baseactivity extends activity {    @inject navigator navigator;    @override   protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     this.getapplicationcomponent().inject(this);   }    protected activitymodule getactivitymodule() {     return new activitymodule(this);   }  }

still unable understand why presenter null in splashactivity

here splash presenter

@peractivity public class splashpresenter implements  presenter {      private final usecase isuserloggedin;      private splashview splashview;      @inject     public splashpresenter(@named("isuserloggedin") usecase isuserloggedin) {         this.isuserloggedin = isuserloggedin;     } }

the instance of logincomponent creates after inject method.

move component initializer custom application class. or move component initializer baseactivity, inject method slashactivity

and makes inject declaration each activity want inject instance @ component interface.

node.js - How do I prevent MongoDB replica set from querying the primary? -

read-operations-only: is there way have mongodb replica set, make mongodb instance on box connected to, mongodb gets queried? i have 3 ec2 instances behind aws load balancer. on each ec2 instance runs mongodb, part of replica set. i have express endpoints on nodejs , connect replica set follows mongodb.mongoclient.connect('mongodb://1.1.1.1,2.2.2.2,3.3.3.3.', function (err, db) { if (err) { complete('{}'); } else { i distribute load of queries evenly across 3 instances of mongodb replica set instead of default having queries routed ec2 instance primary mongodb defined, because destroys point of load balancer (which balance load of queries across 3 instances evenly). my understanding when connecting mongodb replica set, primary instance selected unless primary instance down, , therefore purpose of every secondary instance serve backup. in example people call hot,cold,cold. because there 2...
