Catmandu::Fix::Condition(3pm) User Contributed Perl Documentation Catmandu::Fix::Condition(3pm)

NAME

Catmandu::Fix::Condition - Role for all Catmandu::Fix conditionals

SYNOPSIS

        if <Catmandu::Fix::Condition instance>
                <pass_fixes>
        else
                <fail_fixes>
        end

DESCRIPTION

All Catmandu::Fix conditions need to implement Catmandu::Fix::Condition. This subclass of Catmandu::Fix::Base provides a list of fixes that need to be executed when a conditional matches (pass_fixes) and conditional that need to be executed when a conditional fails (fail_fixes).

Conditions can be used as inline fixes as well:

    use Catmandu::Fix::Condition::exists as => 'has_field';
    
    my $item = { foo => { bar => 1 } };

    has_field($item, 'foo.bar');    # true
    has_field($item, 'doz');        # false
