Interface DataGraph

All Superinterfaces:

java.io.Serializable

All Known Implementing Classes:

SDODataGraph

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.
