An engine to port data between two DataNodes. These nodes can potentially connect to databases from different vendors. The only assumption is that all of the DbEntities (tables) being ported are present in both source and destination databases and are adequately described by Cayenne mapping.

DataPort implements a Cayenne-based algorithm to read data from source DataNode and write to destination DataNode. It uses DataPortDelegate interface to externalize various things, such as determining what entities to port (include/exclude from port based on some criteria), logging the progress of port operation, qualifying the queries, etc.

@since 1.2: Prior to 1.2 DataPort classes were a part of cayenne-examples package.

        List<DataEdge> edges = getEdges();
        QName parameterType = super.getParameterType();
        if (parameterType == null && getEdges().size() > 0) {
            // This happens when the graph XML doesn't have parameterType.
            DataEdge edge = edges.get(0);
            DataPort toPort = edge.getToPort();
            parameterType = toPort.getType();
        }
        return parameterType;
    }

        AntDataPortDelegate portDelegate = new AntDataPortDelegate(
                this,
                maps,
                includeTables,
                excludeTables);
        DataPort dataPort = new DataPort(portDelegate);
        dataPort.setEntities(getAllEntities(source, destination));
        dataPort.setCleaningDestination(cleanDest);
        dataPort.setSourceNode(source);
        dataPort.setDestinationNode(destination);


        try {
            dataPort.execute();
        }
        catch (Exception e) {
            Throwable topOfStack = Util.unwindException(e);
            throw new BuildException(
                    "Error porting data: " + topOfStack.getMessage(),
