NAME
Wikibase::Datatype::Struct::MediainfoSnak - Wikibase mediainfo snak structure serialization.
SYNOPSIS
use Wikibase::Datatype::Struct::MediainfoSnak qw(obj2struct struct2obj);
my $struct_hr = obj2struct($obj, $base_uri);
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, $base_uri);
Convert Wikibase::Datatype::MediainfoSnak instance to structure. $base_uri
is base URI of Wikibase system (e.g. http://test.wikidata.org/entity/).
Returns reference to hash with structure.
struct2obj
my $obj = struct2obj($struct_hr);
Convert structure of mediainfo snak to object.
Returns Wikibase::Datatype::MediainfoSnak instance.
ERRORS
obj2struct():
Base URI is required.
Object doesn't exist.
Object isn't 'Wikibase::Datatype::MediainfoSnak'.
EXAMPLE1
use strict;
use warnings;
use Data::Printer;
use Wikibase::Datatype::MediainfoSnak;
use Wikibase::Datatype::Struct::MediainfoSnak qw(obj2struct);
use Wikibase::Datatype::Value::Item;
# Object.
# instance of (P31) human (Q5)
my $obj = Wikibase::Datatype::MediainfoSnak->new(
'datavalue' => Wikibase::Datatype::Value::Item->new(
'value' => 'Q5',
),
'property' => 'P31',
);
# Get structure.
my $struct_hr = obj2struct($obj, 'http://test.wikidata.org/entity/');
# Dump to output.
p $struct_hr;
# Output:
# \ {
# datavalue {
# type "wikibase-entityid",
# value {
# entity-type "item",
# id "Q5",
# numeric-id 5
# }
# },
# property "P31",
# snaktype "value"
# }
EXAMPLE2
use strict;
use warnings;
use Wikibase::Datatype::Struct::MediainfoSnak qw(struct2obj);
# Item structure.
my $struct_hr = {
'datavalue' => {
'type' => 'wikibase-entityid',
'value' => {
'entity-type' => 'item',
'id' => 'Q5',
'numeric-id' => 5,
},
},
'property' => 'P31',
'snaktype' => 'value',
};
# Get object.
my $obj = struct2obj($struct_hr);
# Get value.
my $datavalue = $obj->datavalue->value;
# Get property.
my $property = $obj->property;
# Get snak type.
my $snaktype = $obj->snaktype;
# Print out.
print "Property: $property\n";
print "Value: $datavalue\n";
print "Snak type: $snaktype\n";
# Output:
# Property: P31
# Value: Q5
# Snak type: value
