NAME

MooseX::Role::JSONObject::Meta::Trait - rename a JSONObject attribute

SYNOPSIS

    package foo;
    
    use Moose;
    use MooseX::Role::JSONObject::Meta::Trait;

    with 'MooseX::Role::JSONObject';
    
    has ipv4_address => (
      is => 'rw',
      isa => 'Str',
      traits => ['JSONAttribute'],
      json_attr => 'IPv4 Address',
    );

    ...
    
    my %data = ('IPv4 Address' => '127.0.0.1');
    my $o = foo->from_json(\%data);
    say $o->ipv4_address;

DESCRIPTION

The MooseX::Role::JSONObject::Meta::Trait trait enhances the MooseX::Role::JSONObject role by allowing an attribute to be stored or retrieved from a hash element with a different name. This may be useful when parsing or outputting data with key names containing whitespace or other characters not well suited for use in a Moose attribute name.

The trait may also be accessed by its JSONAttribute alias.

PROPERTIES

The MooseX::Role::JSONObject::Meta::Trait trait provides a single property:

• json_attr

  Specify the name of the hash key that this attribute should be stored to or retrieved from.
