Magic ANetResponseType::getTransactionResponse method?

[alexsasharegan]

I'm having a hard time following the sample SDK code for parsing responses. All the sample code uses this line after constructing a controller and executing a response:

<?php

$response  = $controller->executeWithApiResponse( 
  \net\authorize\api\constants\ANetEnvironment::SANDBOX
);
$tresponse = $response->getTransactionResponse();

The getTransactionResponse method does not exist in the method. I was expecting to see a __call() method that reflects the method name and accesses the corresponding property, or a class being extended where this method was present, but I didn't find anything.

Is there some php magic here that I'm missing? I would really love to know how this ticks. It's hard to use an SDK with methods that aren't enumerated in the code!

getTransactionResponse() is part of the Authorize.Net PHP SDK. It's defined here in the php sdk.
