=head1 SYNOPSIS
The L<Net::Riak::Bucket> object allows you to access and change information about a Riak bucket, and provides methods to create or retrieve objects within the bucket.
=head1 DESCRIPTION
=head2 ATTRIBUTES
=item B<name>
Get the bucket name
=item B<r>
R value setting for this client (default 2)
=item B<w>
W value setting for this client (default 2)
=item B<dw>
DW value setting for this client (default 2)
=head2 METHODS
=method new_object
Create a new L<Net::Riak::Object> object that will be stored as JSON.
=method get
Retrieve a JSON-encoded object from Riak
=method n_val
Get/set the N-value for this bucket, which is the number of replicas that will be written of each object in the bucket. Set this once before you write any data to the bucket, and never change it again, otherwise unpredictable things could happen. This should only be used if you know what you are doing.
=method allow_multiples
If set to True, then writes with conflicting data will be stored and returned to the client. This situation can be detected by calling has_siblings() and get_siblings(). This should only be used if you know what you are doing.
=method set_property
Set a bucket property. This should only be used if you know what you are doing.
=method get_property
Retrieve a bucket property
=method set_properties
Set multiple bucket properties in one call. This should only be used if you know what you are doing.
=method get_properties
Retrieve an associative array of all bucket properties.
