javascript - How to asynchronously update AngularJS state using value inside of Promise -


how can access returned value then() in javascript?

i have following function:

function getresult(){   var promise = _myservice.getage();   var getresultpromise = promise.then(function(age){     return age;   })   return getresultpromise; //how age (value) here?  *see image* }

or how access value in $$state object below?

enter image description here

how this:

//the simple solution, how use promise:    let _myservice = {    getage: function() {      return new promise(function(resolve, reject) {        settimeout(function() {          resolve(3)        }, 500);      })    }  };    function getresult() {    _myservice.getage().then(function(age) {      console.log(age);    });  }    getresult();    //or, maybe closer op's intended implementation, put value in outer state:    let outerstate = {    age: 0  };    settimeout(function() {    console.log(outerstate)  }, 450);    let _myservice2 = {    getage: function() {      return new promise(function(resolve, reject) {        settimeout(function() {          resolve(8)        }, 750);      })    }  };    function addagetoouterstate() {    pstate = new promise(function(resolve, reject) {      _myservice2.getage().then(function(newage) {        outerstate.age = newage;        resolve(outerstate);      });    });      pstate.then(function() {      console.log(outerstate);    });      return pstate;  }    addagetoouterstate()    //for fun  .then(function(outer) {    console.log(outer); //state still here  });

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
