This object returned from one of *asynchronous* detect methods that represents a running detector on the call.

## Methods

### getControlId

Return the UUID to identify the action.

**Parameters**

*None*

**Returns**

`string` - UUID to identify the action.

**Examples**

Start a detector and print the controlId.

```php
<?php

$call->detectMachineAsync()->done(function ($action) {
  echo $action->getControlId();
});
```

### getPayload

Return the payload sent to Relay to initiate the request. Useful to inspect what you sent to perform this action.

**Parameters**

*None*

**Returns**

`Object` - Payload sent to Relay.

**Examples**

Start a detector and print out the payload.

```php
<?php

$call->detectDigitAsync()->done(function($detectResult) {
  print_r($action->getPayload());
});
```

### getResult

Returns the final detector result.

**Parameters**

*None*

**Returns**

[`Relay.Calling.DetectResult`][relay-calling-detectresult] - Final detector result.

**Examples**

Trying detecting DTMF and grab the result when it's completed.

```php
<?php

$call->detectDigitAsync()->done(function($action) {
  // .. later in the code since it's an async method
  if ($action->isCompleted()) {
    $detectResult = $action->getResult();
  }
});
```

### isCompleted

Return `true` if detector has finished, `false` otherwise.

**Parameters**

*None*

**Returns**

`Boolean` - True/False accordingly to the state.

**Examples**

Trying detecting DTMF and check if it has finished.

```php
<?php

$call->detectDigitAsync()->done(function($action) {
  // .. later in the code since it's an async method
  if ($action->isCompleted()) {

  }
});
```

### stop

Stop the action immediately.

**Parameters**

*None*

**Returns**

`React\Promise\Promise` - Promise object that will be fulfilled with a [`Relay.Calling.StopResult`][relay-calling-stopresult] object.

**Examples**

Trying detecting a machine and then stop the action.

```php
<?php

$call->detectMachineAsync()->done(function ($action) {
  // For demonstration purposes only..
  $action->stop()->done(function($stopResult) {

  });
});
```
