Examples of com.basho.riak.client.bucket.Bucket

com.basho.riak.client.bucket.Bucket
The primary interface for working with Key/Value data in Riak, a factory for key/value {@link RiakOperation}s.
Provides convenience methods for creating {@link RiakOperation}s for storing byte[] and String data in Riak. Also provides methods for creating {@link RiakOperation}s for storing Java Bean style POJOs in Riak. A Bucket is a factory for {@link RiakOperation}s on Key/Value data.

Gives access to all the {@link BucketProperties} that the underlying APItransport exposes. NOTE: soon this will be *all* the {@link BucketProperties}

Provides access to an {@link Iterable} for the keys in the bucket.
