Net::Riak::Object(3) User Contributed Perl Documentation Net::Riak::Object(3) NAME Net::Riak::Object - holds meta information about a Riak object VERSION version 0.1702 SYNOPSIS my $obj = $bucket->get('foo'); DESCRIPTION The Net::Riak::Object holds meta information about a Riak object, plus the object's data. ATTRIBUTES key my $key = $obj->key; Get the key of this object client bucket data Get or set the data stored in this object. r w dw content_type links Get an array of Net::Riak::Link objects exists Return true if the object exists, false otherwise. siblings Return an array of Siblings METHODS all_links Return the number of links has_links Return the number of links append_link Add a new link get_siblings Return the number of siblings add_sibling Add a new sibling count_siblings get_sibling Return a sibling all_meta Returns a hash containing all the meta name/value pairs my %metadata = $obj->all_meta; has_meta Returns the number of usermetas associated with the object. Typical use is as a predicate method. if ( $obj->has_meta ) { ... } set_meta Sets a usermeta on the object, overriding any existing value for that key $obj->set_meta( key => $value ); get_meta Reads a single usermeta from the object. If multiple usermeta headers have been set for a single key (eg via another client), the values will be separated with a comma; Riak will concatenate the input headers and only return a single one. remove_meta removes a single usermeta from the object. Returns false on failure, eg if the key did not exist on the object. $obj->remove_meta( 'key' ) || die( "could not remove" ); store $obj->store($w, $dw); Store the object in Riak. When this operation completes, the object could contain new metadata and possibly new data if Riak contains a newer version of the object according to the object's vector clock. w W-value, wait for this many partitions to respond before returning to client. dw DW-value, wait for this many partitions to confirm the write before returning to client. load $obj->load($w); Reload the object from Riak. When this operation completes, the object could contain new metadata and a new value, if the object was updated in Riak since it was last retrieved. r R-Value, wait for this many partitions to respond before returning to client. delete $obj->delete($dw); Delete this object from Riak. dw DW-value. Wait until this many partitions have deleted the object before responding. clear $obj->reset; Reset this object has_siblings if ($obj->has_siblings) { ... } Return true if this object has siblings has_no_siblings if ($obj->has_no_siblings) { ... } Return true if this object has no siblings populate_object Given the output of RiakUtils.http_request and a list of statuses, populate the object. Only for use by the Riak client library. add_link $obj->add_link($obj2, "tag"); Add a link to a Net::Riak::Object remove_link $obj->remove_link($obj2, "tag"); Remove a link to a Net::Riak::Object add Start assembling a Map/Reduce operation link Start assembling a Map/Reduce operation map Start assembling a Map/Reduce operation reduce Start assembling a Map/Reduce operation AUTHOR franck cuny <franck@lumberjaph.net>, robin edwards <robin.ge@gmail.com> COPYRIGHT AND LICENSE This software is copyright (c) 2013 by linkfluence.
