The Errorhandler consists of 3 Layers.

User input

ErrorHandlerGW is an easy-to access, userfriendly interface to the ErrorHandler. It validates input and translates it to calls to the ErrorHandler.

Error Handling

ErrorHandler catches the Errors that come in from error_reporting, decides if they should be handled or ignored, cleans the Error backtrace and puts all this information in the Error Object.

Error Display

An ErrorProcessor can register at the ErrorHandler and will be notified of any occuring Error. It uses the Error-Object to generate an output using an ErrorRender and sends/delivers/saves this Output.
