Pulling exception page rendering out into a separate class, ErrorHandler felt very large and confusing, as it had a few too many jobs.

/**

* Exception Renderer.
|
||||
*
|
||||
* Captures and handles all unhandled exceptions. Displays helpful framework errors when debug > 1.
|
||||
* When debug < 1 a CakeException will render 404 or 500 errors. If an uncaught exception is thrown
|

* and it is a type that ExceptionHandler does not know about it will be treated as a 500 error.
|
||||
*
|
||||
* ### Implementing application specific exception handling
|
||||
*
|
||||
* You can implement application specific exception handling in one of a few ways:
|
||||
*
|
||||
* - Create a AppController::appError();
|
||||
* - Create an AppError class.
|
||||
*
|
||||
* #### Using AppController::appError();
|
||||
*
|
||||
* This controller method is called instead of the default exception handling. It receives the
|
||||
* thrown exception as its only argument. You should implement your error handling in that method.
|
||||
*
|
||||
* #### Using an AppError class
|
||||
*
|
||||
* This approach gives more flexibility and power in how you handle exceptions. You can create
|
||||
* `app/libs/app_error.php` and create a class called `AppError`. The core ErrorHandler class
|
||||
* will attempt to construct this class and let it handle the exception. This provides a more
|
||||
* flexible way to handle exceptions in your application.
