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.
