SQL::Translator::Role::Error - Error setter/getter for objects and classes
In the class consuming the role:
package Foo; use Moo; with qw(SQL::Translator::Role::Error); sub foo { ... return $self->error("Something failed") unless $some_condition; ... }
In code using the class:
Foo->foo or die Foo->error; # or $foo->foo or die $foo->error;
This Moo::Role provides a method for getting and setting error on a class or object.
If called with an argument, sets the error message and returns undef, otherwise returns the message.
As an implementation detail, for compatibility with Class::Base, the message is stored in $object->{_ERROR} or $Class::ERROR, depending on whether the invocant is an object.
$object->{_ERROR}
$Class::ERROR
