NAME
Net::Fritz::IsNoError - a Moo::Role discerning all other Net::Fritz objects from a Net::Fritz::Error object
VERSION
version v0.0.6
SYNOPSIS
$root_device = Net::Fritz::Box->new->discover;
$root_device->errorcheck;
or
$root_device = Net::Fritz::Box->new->discover;
if ($root_device->error) {
die "error: " . $root_device->error;
}
DESCRIPTION
All valid (non-error) Net::Fritz classes do the Net::Fritz::IsNoError role, the only exception being of course) Net::Fritz::Error. All Net::Fritz objects thus support error
and errorcheck
If you want your code to just die()
on any error, call $obj-
errorcheck> on every returned object (see first example above).
If you just want to check for an error and handle it by yourself, call $obj->error
. All non-errors will return 0
(see second example above).
You don't have to check for errors at all, but then you might run into problems when you want to invoke methods on an Net::Fritz::Error object that don't exist (because you expected to get eg. an Net::Fritz::Service object instead).
ATTRIBUTES (read-only)
error
Returns an empty string to pass any if($obj->error) { ... }
checks.
METHODS
errorcheck
A no-op, so that calling $obj->errorcheck
just succeeds and carries on.
