NAME¶
Log::Report::Exception - a collected reportSYNOPSIS¶
# created within a try block
try { error "help!" };
my $exception = $@->wasFatal;
$exception->throw if $exception;
$@->reportFatal; # combination of above two lines
my $message = $exception->message; # the Log::Report::Message
if($message->inClass('die')) ...
if($exception->inClass('die')) ... # same
if($@->wasFatal(class => 'die')) ... # same
DESCRIPTION¶
In Log::Report, exceptions are not as extended as available in languages as Java: you do not create classes for them. The only thing an exception object does, is capture some information about an (untranslated) report.METHODS¶
Constructors¶
- Log::Report::Exception->new(%options)
-
-Option --Default message <required> reason <required> report_opts {}
- message => Log::Report::Message
- reason => REASON
- report_opts => HASH
Accessors¶
- $obj->isFatal()
- Returns whether this exception has a severity which makes it fatal when
thrown. See Log::Report::Util::is_fatal().
example:
if($ex->isFatal) { $ex->throw(reason => 'ALERT') } else { $ex->throw } - $obj->message( [$message] )
- Change the $message of the exception, must be a
Log::Report::Message object.
When you use a "Log::Report::Message" object, you will get a new one returned. Therefore, if you want to modify the message in an exception, you have to re-assign the result of the modification.
example:
$e->message->concat('!!')); # will not work! $e->message($e->message->concat('!!')); $e->message(__x"some message {msg}", msg => $xyz); - $obj->reason( [$reason] )
- $obj->report_opts()
Processing¶
- $obj->inClass($class|Regexp)
- Check whether any of the classes listed in the message match $class (string) or the Regexp. This uses Log::Report::Message::inClass().
- $obj->print( [$fh] )
- The default filehandle is STDOUT.
example:
print $exception; # via overloading $exception->print; # OO style - $obj->throw(%options)
- Insert the message contained in the exception into the currently defined
dispatchers. The "throw" name is
commonly known exception related terminology for
"report".
The %options overrule the captured options to Log::Report::report(). This can be used to overrule a destination. Also, the reason can be changed.
example: overrule defaults to report
try { print {to => 'stderr'}, ERROR => 'oops!' }; $@->reportFatal(to => 'syslog'); $exception->throw(to => 'syslog'); $@->wasFatal->throw(reason => 'WARNING'); - $obj->toHTML( [$locale] )
- [1.11] as toString(), and escape HTML volatile characters.
- $obj->toString( [$locale] )
- Prints the reason and the message. Differently from throw(), this
only represents the textual content: it does not re-cast the exceptions to
higher levels.
example: printing exceptions
print $_->toString for $@->exceptions; print $_ for $@->exceptions; # via overloading
OVERLOADING¶
- overload: stringification
- Produces "reason: message".
