NAME
Log::Report::Exception - a collected report
SYNOPSIS
# 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 {}
Accessors
- $obj->isFatal()
-
Returns whether this exception has a severity which makes it fatal when thrown. See Log::Report::isFatal().
example:
if($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|REGEX)
-
Check whether any of the classes listed in the message match CLASS (string) or the REGEX. This uses Log::Report::Message::inClass().
- $obj->print([FILEHANDLE])
-
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 forreport
.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->toString()
-
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
