I am trying to create exception class hierarchy. But I think I am not declaring them correctly as I am not able to refer to the exception objects.
use Exception::Class (
'MyException',
'Commands' => { isa => 'MyException' },
'Timeout' => {
isa => 'Commands',
description =>
'These exceptions are resulted from running the metrics comm
+ands'
},
'DBError' => {
isa => 'MyException',
description => 'DB returned error'
}
);
ThrowMyException();
sub ThrowMyException() {
eval{MyException::Commands::Timeout->throw(error=>"This is error d
+ue to timeout");};
my $err;
if($err=Exception::Class->caught('MyException::Commands::Timeo
+ut')){
#print Dumper($err);
#print "err is of type ".ref($err);
die $err->{"description"}.": ".$err->{"error"};
}
elsif ( $err = Exception::Class->caught("MetricsException") )
+{
#print Dumper($err);
die $err->error;
}
}
Can somebody see what is wrong with the code?
