Interface DataGraph

  • All Superinterfaces:
    Serializable
    All Known Implementing Classes:
    SDODataGraph
    public interface DataGraph
extends Serializable
    Deprecated.
    . Because the same functionality can be obtained with DataObjects alone and because using DataObjects has the advantages of consistence and richer functionality, the use of the special envelope DataGraph is discouraged and may be removed altogether in a future version.
    A data graph is used to package a graph of data objects along with their metadata, that is, data describing the data. A data graph also contains a change summary which is used to record changes made to the objects in the graph.
