javascript - .asObservable dont want to work with Observable.forkJoin -


i have service:

export class configservice {   private _config: behaviorsubject<object> = new behaviorsubject(null);   public config: observable<object> = this._config.asobservable();    constructor(private api: apiservice) {     this.loadconfigs();   }    loadconfigs() {    this.api.get('/configs').subscribe( res => this._config.next(res) );   } }

trying call component: 

... observable.forkjoin([someservice.config])   .subscribe( res => console.log(res) ) //not working   someservice.config.subscribe( res => console.log(res) ) // working ...

how can use observable.forkjoin observable variable config?

i need store configs in service , wait unlit them , others request not finished stop loader.

since you're using behaviorsubject should know can call next() , complete() manually.

the forkjoin() operator emits when of source observables have emitted @ least 1 values and completed. since you're using subject , asobservable method source observable never completes , forkjoin operator never emits anything.

btw, doesn't make sense use forkjoin 1 source observable. maybe have @ zip() or combinelatest() operators similar , maybe it's need.

two similar question:

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...
