NAME

Wikibase::Datatype::Struct::Value::Item - Wikibase item value structure serialization.

SYNOPSIS


            

              
              
use Wikibase::Datatype::Struct::Value::Item qw(obj2struct struct2obj);
my $struct_hr = obj2struct($obj);
my $obj = struct2obj($struct_hr);

DESCRIPTION

This conversion is between objects defined in Wikibase::Datatype and structures serialized via JSON to MediaWiki.

SUBROUTINES

obj2struct


            

              
              
my $struct_hr = obj2struct($obj);

Convert Wikibase::Datatype::Value::Item instance to structure.

Returns reference to hash with structure.

struct2obj


            

              
              
my $obj = struct2obj($struct_hr);

Convert structure of item to object.

Returns Wikibase::Datatype::Value::Item instance.

ERRORS


            

              
              
obj2struct():
        Object doesn't exist.
        Object isn't 'Wikibase::Datatype::Value::Item'.
struct2obj():
        Structure isn't for 'item' datatype.

EXAMPLE1


            

              
              
use strict;
use warnings;
use Data::Printer;
use Wikibase::Datatype::Value::Item;
use Wikibase::Datatype::Struct::Value::Item qw(obj2struct);
# Object.
my $obj = Wikibase::Datatype::Value::Item->new(
        'value' => 'Q123',
);
# Get structure.
my $struct_hr = obj2struct($obj);
# Dump to output.
p $struct_hr;
# Output:
# \ {
#     type    "wikibase-entityid",
#     value   {
#         entity-type   "item",
#         id            "Q123",
#         numeric-id    123
#     }
# }

EXAMPLE2


            

              
              
use strict;
use warnings;
use Wikibase::Datatype::Struct::Value::Item qw(struct2obj);
# Item structure.
my $struct_hr = {
        'type' => 'wikibase-entityid',
        'value' => {
                'entity-type' => 'item',
                'id' => 'Q123',
                'numberic-id' => 123,
        },
};
# Get object.
my $obj = struct2obj($struct_hr);
# Get value.
my $value = $obj->value;
# Get type.
my $type = $obj->type;
# Print out.
print "Type: $type\n";
print "Value: $value\n";
# Output:
# Type: item
# Value: Q123
