      my $service = $client->service('ELB');

      # Apply waiter role to Paws class
      PawsX::Waiter->meta->apply($service);
      my $response = $service->RegisterInstancesWithLoadBalancer(

         Instances        => [ { InstanceId => 'i-0xxxxx'  } ]
      );

      my $waiter = $service->GetWaiter('InstanceInService');

         {
            LoadBalancerName => 'test-elb',

# DESCRIPTION

Waiters are utility methods that poll for a particular state to occur on a client. Waiters can fail after a number of attempts at a polling interval defined for the service client.

# METHODS

## GetWaiter

    my $waiter = $service->GetWaiter('InstanceInService');
    

This method returns a new PawsX::Waiter object and It has the following attributes. You can configure the waiter behaviour with this.

### delay(Int)

    $waiter->delay(10);
    

Number of seconds to delay between polling attempts. Each waiter has a default delay configuration value, but you may need to modify this setting for specific use cases.

### maxAttempts(Int)

    $waiter->maxAttempts(100);
    

Maximum number of polling attempts to issue before failing the waiter. Each waiter has a default maxAttempts configuration value, 
but you may need to modify this setting for specific use cases.

### wait(HashRef)

     $waiter->wait(
         {
            LoadBalancerName => 'test-elb',
            Instances        => [ { InstanceId => 'i-0xxxxx' } ],
        }
      );

Block until the waiter completes or fails.Note that this might throw a PawsX::Exception::\* if the waiter fails.
