NAME

SQL::Translator::Role::Error − Error setter/getter for objects and classes

SYNOPSIS

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;

DESCRIPTION

This Moo::Role provides a method for getting and setting error on a class or object.

METHODS

$object_or_class−>error([$message])

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.
