NAME

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

SYNOPSIS

 use Wikibase::Datatype::Struct::Value 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::Value 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 value to object.

Returns Wikibase::Datatype::Value instance.

ERRORS

 obj2struct():
         Object doesn't exist.
         Object isn't 'Wikibase::Datatype::Value'.
         Type '%s' is unsupported.

 struct2obj():
         Entity type '%s' is unsupported.
         Type doesn't exist.
         Type '%s' is unsupported.

EXAMPLE1

 use strict;
 use warnings;

 use Data::Printer;
 use Wikibase::Datatype::Value::Time;
 use Wikibase::Datatype::Struct::Value qw(obj2struct);

 # Object.
 my $obj = Wikibase::Datatype::Value::Time->new(
         'precision' => 10,
         'value' => '+2020-09-01T00:00:00Z',
 );

 # Get structure.
 my $struct_hr = obj2struct($obj, 'http://test.wikidata.org/entity/');

 # Dump to output.
 p $struct_hr;

 # Output:
 # \ {
 #     type    "time",
 #     value   {
 #         after           0,
 #         before          0,
 #         calendarmodel   "http://test.wikidata.org/entity/Q1985727",
 #         precision       10,
 #         time            "+2020-09-01T00:00:00Z",
 #         timezone        0
 #     }
 # }

EXAMPLE2

 use strict;
 use warnings;

 use Wikibase::Datatype::Struct::Value qw(struct2obj);

 # Time structure.
 my $struct_hr = {
         'type' => 'time',
         'value' => {
                 'after' => 0,
                 'before' => 0,
                 'calendarmodel' => 'http://test.wikidata.org/entity/Q1985727',
                 'precision' => 10,
                 'time' => '+2020-09-01T00:00:00Z',
                 'timezone' => 0,
         },
 };

 # Get object.
 my $obj = struct2obj($struct_hr);

 # Get calendar model.
 my $calendarmodel = $obj->calendarmodel;

 # Get precision.
 my $precision = $obj->precision;

 # Get type.
 my $type = $obj->type;

 # Get value.
 my $value = $obj->value;

 # Print out.
 print "Calendar model: $calendarmodel\n";
 print "Precision: $precision\n";
 print "Type: $type\n";
 print "Value: $value\n";

 # Output:
 # Calendar model: Q1985727
 # Precision: 10
 # Type: time
 # Value: +2020-09-01T00:00:00Z
