NAME

Wikibase::Datatype::MediainfoStatement - Wikibase mediainfo statement datatype.

SYNOPSIS

 use Wikibase::Datatype::MediainfoStatement;

 my $obj = Wikibase::Datatype::MediainfoStatement->new(%params);
 my $id = $obj->id;
 my $property_snaks_ar = $obj->property_snaks;
 my $rank = $obj->rank;
 my $referenes_ar = $obj->references;
 my $snak = $obj->snak;

DESCRIPTION

This datatype is statement class for representing mediainfo statement.

METHODS

new

 my $obj = Wikibase::Datatype::MediainfoStatement->new(%params);

Constructor.

Returns instance of object.

  Rank value. Parameter is string with these possible values: normal, preferred and deprecated Default value is 'normal'.

• references

  List of references. Parameter is reference to hash with Wikibase::Datatype::Reference instances. Parameter is optional. Default value is [].

• snak

  Main snak. Parameter is Wikibase::Datatype::MediainfoSnak instance. Parameter is required.

id

 my $id = $obj->id;

Get id of statement.

Returns string.

property_snaks

 my $property_snaks_ar = $obj->property_snaks;

Get property mediainfo snaks.

Returns reference to array with Wikibase::Datatype::MediainfoSnak instances.

rank

 my $rank = $obj->rank;

Get rank value.

references

 my $referenes_ar = $obj->references;

ERRORS

 new():
         From Mo::utils::check_array_object():
                 Parameter 'property_snaks' must be a array.
                 Parameter 'references' must be a array.
                 Property mediainfo snak isn't 'Wikibase::Datatype::MediainfoSnak' object.
                 Reference isn't 'Wikibase::Datatype::Reference' object.
         From Mo::utils::check_isa():
                 Parameter 'snak' must be a 'Wikibase::Datatype::MediainfoSnak' object.
         From Mo::utils::check_required():
                 Parameter 'snak' is required.
         Parameter 'rank' has bad value. Possible values are normal, preferred, deprecated.
