| /**
 | |
|  * A generic ErrorHandler for the PHP engine.
 | |
|  *
 | |
|  * Provides five bit fields that control how errors are handled:
 | |
|  * - thrownErrors: errors thrown as \ErrorException
 | |
|  * - loggedErrors: logged errors, when not @-silenced
 | |
|  * - scopedErrors: errors thrown or logged with their local context
 | |
|  * - tracedErrors: errors logged with their stack trace
 | |
|  * - screamedErrors: never @-silenced errors
 | |
|  *
 | |
|  * Each error level can be logged by a dedicated PSR-3 logger object.
 | |
|  * Screaming only applies to logging.
 | |
|  * Throwing takes precedence over logging.
 | |
|  * Uncaught exceptions are logged as E_ERROR.
 | |
|  * E_DEPRECATED and E_USER_DEPRECATED levels never throw.
 | |
|  * E_RECOVERABLE_ERROR and E_USER_ERROR levels always throw.
 | |
|  * Non catchable errors that can be detected at shutdown time are logged when the scream bit field allows so.
 | |
|  * As errors have a performance cost, repeated errors are all logged, so that the developer
 | |
|  * can see them and weight them as more important to fix than others of the same level.
