RarException::setUsingExceptions — Activate and deactivate error handling with exceptions

Opis

public static RarException::setUsingExceptions ( bool $using_exceptions ) : void

If and only if the argument is TRUE, then, instead of emitting warnings and returning a special value indicating error when the UnRAR library encounters an error, an exception of type RarException will be thrown.

Exceptions will also be thrown for the following errors, which occur outside the library (their error code will be -1):

attempting some operations on a closed RarArchive object or a RarEntry object relative to the first;
attempting to get an entry that does not exist with RarArchive::getEntry().

Parametry

using_exceptions: Should be TRUE to activate exception throwing, FALSE to deactivate (the default).
