NG5- Share Data using Service as Subject (short hand) and BehaviourSubject
--------------------------------------------------------------------------
Behaviour subject get's called before the receiver component comes to load.
Subject based service used to load if, the receiver component is in DOM

Common.service.ts
------------------
import { Injectable } from '@angular/core';
import { Subject } from 'rxjs/Subject';
import {BehaviorSubject, Observable} from "rxjs/Rx";

@Injectable()
export class CommonService {

  private type1 = new Subject<{flag:false}>();
  private type2 = new Subject<{flag:false}>();
  private type3: BehaviorSubject<{}> = new BehaviorSubject({flag:false});

  // method:1
  setValue1(message) {
    this.type1.next(message);
  }
  getValue1(): Observable<any> {
    return this.type1.asObservable();
  }
  // method:2
  swapValue(val){
    this.type2.next(val);
  }
  getcandidateQRow = this.type2.asObservable();
  //method:3
  setValue3(edit){
    this.type3.next(edit);
  }
  getValue3(){
    return this.type3;
  }
 
  }
 

component1-sender.ts
--------------------

inject Service

constructor( private service: CommonService){}

this.service.setValue1(this.selectedTableRow);
this.service.swapValue(this.selectedTableRow);
this.service.setValue3(this.selectedTableRow);


component2-receiver.ts
----------------------

inject Service

constructor( private service: CommonService){

this.service.getCQRowEdit().subscribe(
      res => {
        let temp;
        temp = res;       
        console.log(res,'Behaviour Subject');
      });
    this.addToSubscriptList(subscription);
this.service.getCQRow().subscribe(
      res => {
        let temp;
        temp = res;
        console.log(res, 'subject');
      });
  responed;
service.getcandidateQRow.subscribe( res =>{

      viewRow =>this.responed= viewRow;
      console.log(this.responed,'code elimination subject');
    });
}
