NAME

Wikibase::Datatype::Struct::Form - Wikibase form structure serialization.

SYNOPSIS

 use Wikibase::Datatype::Struct::Form 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::Form 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 form to object.

Returns Wikibase::Datatype::Form instance.

ERRORS

 obj2struct():
         Base URI is required.
         Object doesn't exist.
         Object isn't 'Wikibase::Datatype::Form'.
