  - wikibase-property (Wikibase::Datatype::Value::Property)
  - wikibase-sense (Wikibase::Datatype::Value::Sense)

• datavalue

  Value of data in form of Wikibase::Datatype::Value instance for concrete datatype. Parameter is required in situation when snaktype = 'value'.

• property

• snaktype

  Snak type. Parameter is string with these possible values: novalue somevalue value Parameter is optional. Default value is 'value'.

datavalue

my $datavalue = $obj->datavalue;

Get data value.

Returns instance of Wikibase::Datatype::Value.

property

my $property = $obj->property;

ERRORS

new():
        From Mo::utils::check_required():
                Parameter 'datatype' is required.
                Parameter 'datavalue' is required.
                Parameter 'property' is required.
        From Mo::utils::check_isa():
                Parameter 'datavalue' must be a 'Wikibase::Datatype::Value::%s' object.
        From Wikibase::Datatype::Utils::check_property():
                Parameter 'property' must begin with 'P' and number after it.
        Parameter 'datatype' = '%s' isn't supported.
        Parameter 'snaktype' = '%s' isn't supported.

EXAMPLE

use strict;
use warnings;

use Wikibase::Datatype::Snak;
use Wikibase::Datatype::Value::Item;

# Object.
my $obj = Wikibase::Datatype::Snak->new(
        'datatype' => 'wikibase-item',
        'datavalue' => Wikibase::Datatype::Value::Item->new(
                'value' => 'Q5',
        ),
        'property' => 'P31',
);

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

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

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

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

# Print out.
print "Property: $property\n";
print "Type: $datatype\n";
print "Value: $datavalue\n";
print "Snak type: $snaktype\n";

# Output:
# Property: P31
# Type: wikibase-item
# Value: Q5
# Snak type: value
