JDBC mediator serialization
The DataGraph produced by the JDBC DMS can be serialized and written out to a file, or sent across a network.
The following example illustrates serialization and de-serialization of a graph:
// This example assumes the creation of the Customer // metadata and the JDBC DMS. DataObject object = mediator.getGraph(); DataGraph origGraph = object.getDataGraph(); FileOutputStream out = new FileOutputStream("test.datagraph"); ObjectOutputStream oos = new ObjectOutputStream(out); oos.writeObject(origGraph); out.close(); FileInputStream in = new FileInputStream("test.datagraph"); ObjectInputStream oin = new ObjectInputStream(in); DataGraph graph = (DataGraph) oin.readObject(); DataObject obj = (DataObject) graph.getRootObject(); // Now, the DataObject retrieved from the input stream // obj is equal to the original variable object put // through the output stream.
