Examples of com.basho.riak.client.IRiakObject

com.basho.riak.client.IRiakObject
Represents the data and meta data stored in Riak at a bucket/key.
Although you can store your own Java Beans in Riak, this interface represents the core data type that is passed between the low and high level APIs and that all POJOs are converted to and from when stored or fetched.

Extends {@link Iterable} to provide a simple way to iterate over thecollection of {@link RiakLink}s.

NOTE: The name will be changing soon. The initial Java client release laid claim to the best name real estate. This class will be named RiakObject in subsequent releases.
