Examples of commonj.sdo.DataGraph

commonj.sdo.DataGraph
A data graph is used to package a graph of {@link DataObject data objects} along with theirmetadata, that is, data describing the data. A data graph also contains a {@link #getChangeSummary change summary} which is used to record changes made to the objects in the graph.
