Method Summary

void	readData(Graph2D graph, Object obj, ObjectInputStream in) This method reads data from the given input stream and processes it.
void	writeData(Graph2D graph, Object obj, ObjectOutputStream out) This method writes data to the given input stream.

Method Detail

readData

void readData(Graph2D graph,
              Object obj,
              ObjectInputStream in)
              throws IOException

This method reads data from the given input stream and processes it. The method is being called for each Node, Edge or Graph2D that is contained in the actual input graph.

Throws:

IOException - thrown if something does wrong while reading data.

Parameters:

graph - the graph for which to read data.

obj - a Node, an Edge or the graph itself. This object is directly associated with the actual data.

in - the input stream from which to read data.

writeData

void writeData(Graph2D graph,
               Object obj,
               ObjectOutputStream out)
               throws IOException

This method writes data to the given input stream. The method is being called for each Node, Edge or Graph2D that is contained in the actual input graph.

Throws:

IOException - thrown if something does wrong while writing data.

Parameters:

graph - the graph for which to write data.

obj - a Node, an Edge or the graph itself. This object is directly associated with the actual data.

out - the output stream from which to write data.
