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.
