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.
