[Enhancement] Proper ways of adding getters to classes

[peterzhuamazon]

These are the getters setup today:

automation-app/src/service/operation/operation.ts

Lines 16 to 27 in 9b4854b

	public getName(): string {
	return this.name;
	}
	public getEvents(): string[] {
	return this.events;
	}
	public getTasks(): Task[] {
	return this.tasks;
	}
	}

A better way:

export class Operation {
  private _name: string;
  private _events: string[];
  private _tasks: Task[];

  constructor(name: string, events: string[], tasks: Task[]) {
    this._name = name;
    this._events = events;
    this._tasks = tasks;
  }

  public get name(): string {
    return this._name;
  }

  public get events(): string[] {
    return this._events;
  }

  public get tasks(): Task[] {
    return this._tasks;
  }
}

Even better we can just use readonly:

export class Operation {
  readonly name: string;
  readonly events: string[];
  readonly tasks: Task[];

  constructor(name: string, events: string[], tasks: Task[]) {
    this.name = name;
    this.events = events;
    this.tasks = tasks;
  }
}

Thanks.
